4/10 email
rom: Provost Sent: Friday, April 10, 2020 3:14 PM To: FacultyStaffBroadcast Subject: Some Positive News
Dear Colleagues:
As we approach the end of our truncated spring break, I want to take the opportunity to share some good news for a change. Yesterday we learned that Dr. Valerie Trevere of the Department of Media Culture was recipient of a Guggenheim Fellowship for a collaborative project with Dr. Angel Navarez of the New School. They are among the 175 awardees selected from a field of over 3000 applicants for this prestigious award. This quote from the pair's website (neveraztevere.info) describes their multidisciplinary work:
Tevere and Nevarez “are multidisciplinary artists whose projects and research investigate contemporary music and sound, the electromagnetic spectrum, dissent, and public fora. Their interests lie in the formation of itinerant, performative, and discursive-based social spaces with works that move between the spatial simultaneity of performance and enunciation, reflecting upon political agency through lyrics, audio, and transmission.”
The pair described their Guggenheim project, tentatively titled, A Slow Dropping, as follows: a dispersed musical score, roving from house to house, then sonically assembling in a centralized physical location and an FM broadcast. The musical score will be generated as a site-specific work, where the source of each sound is located in the area of its production. Each musician’s home will become a musical track and personal story coalescing into a unified score, simultaneously fragmented and cohesive, echoing both the social organization of neighborhoods and the mechanics of a recording studio’s mixing board, where individual sound tracks combine to form a field of sonic assembly. A solo exhibition featuring this new project will be presented at the UNO St. Claude Gallery and is curated by Anna Mecugni, Assistant Professor of Art History at the University of New Orleans.
In this era of social distancing, where so many performing artists are limited to performing solo in their homes, this exciting project seems particularly apropos.
COVID-19 has severely impacted the way we all live our daily lives, and one of our History faculty, Dr. Susan Smith-Peter, is leading a team who are taking the opportunity to chronicle an oral and visual history of the pandemic locally in real time. She and her partners in this project have established a Facebook site: CSI Public History Coronavirus Chronicle to solicit and display news and visual artifacts related to our current health and social crisis.
As we move into April, students are starting to hear about their admissions into postgraduate programs. Political Science Chair, Professor, and Pre-Law Advisor Michael Paris is starting to hear once again that his efforts in mentoring prospective law students are once again bearing fruit. Two of his charges, Kaetlyn Goetten and Jake Haymes, have each been accepted to multiple top-tier law schools with full tuition and/or generous financial support.
Finally, Chazanoff School of Business Dean Susan Holak reports that two of their graduates are doing their part to support those affected by the COVID-19 Crisis. Kevin Ferger, a 2019 Marketing graduate, has started a Go Fund Me campaign to 3-D print masks that he will donate to area hospitals. 2015 Marketing Grad Jonathan Saquisilli has created a Volunteer Marketing Clinic which will provide business owners in the Food and Beverage and non-profit sectors free counseling on the use of things like social media, search image optimization, and email to keep their businesses running during a time when such businesses are facing unprecedented challenges.
It is a pleasure to share some really exciting and positive news, and I wish all of you a safe and enjoyable weekend.
Sincerely
Michael
Michael Parrish Provost and Senior Vice President for Academic Affairs

This Week in Rust
Hello and welcome to another issue of This Week in Rust! Rust is a systems language pursuing the trifecta: safe, concurrent, and fast. This is a weekly summary of its progress and community. Want something mentioned? Send me an email! Want to get involved? We love contributions.
What’s cooking in master?
74 pull requests were merged this week.
Breaking Changes
- Struct fields now inherit the privacy of the struct itself.
- A bug in instantiability checking (determining whether a value of a given type could ever be constructed) has been fixed.
Zero
andOne
have been tightened up, and fewer types implement them now.- A lot of things have changed regarding functions that fail or return Options. Almost everything that used to fail now returns an Option instead.
- Many incorrect usages of types from
std::libc
now use Rust types. This might introduce an extraas
or few in code using these (relatively obscure) interfaces. invert
onDoubleEndedIterator
has been renamed torev
.- The numeric constants have been uppercased.
- Some privacy in std and extra has been shuffled around.
Other Changes
- Most macros are no longer injected as a hard-coded string and in fact live in libstd.
- Using
-Z no-landing-pads
actually disables landing pad generation. It was accidentally broken. - The FFI documentation now includes a section on callbacks.
- A lint for unnecessary parens on control flow conditions etc has been added.
- Support for ARM’s thumb instructions has been added.
- libnative now implements timers.
- There is now exponential notation for float formatting.
Vec<T>
has been added, which is intended to eventually replace~[T]
.- Borrow checker errors now have better spans and should be more understandable.
- It is now possible to opt out of using rpaths.
- libnative now implements
get_host_addresses
. - A new synchronization primitive, Barrier, has been added.

Weekly Meeting
The weekly meeting discussed a bunch of open pull requests, but nothing too groudbreaking.
This Week in Servo
Servo is a web browser engine written in Rust and is one of the primary test cases for the Rust language.
This week, we landed 19 PRs and had a Servo workweek in the Mozilla San Francisco office from Tuesday through Friday (Monday was a US federal holiday).
Notable additions
- Bruno Abinader implemented Document::createHTMLDocument in #1523.
- Patrick Walton implemented parallel layout for two of our three layout passes in #1493.
- Patrick Kim fixed computation of image box sizes in #1520 and text-decoration in #1506.
- Deokjin Kim landed the
white-space:pre
property in #1507. - Aydin Kim and Lars Bergstrom landed fixes for Servo on Android.
- Teodor Szente fixed up a type signature in #1541.
- Lars Bergstrom changed ref tests so that they now emit a PNG showing the image-diff between the baseline and incorrect rendering in #1544.
New contributors
- Teodor Szente
Meetings
There was no separate Servo meeting, but during the workweek we discussed details in our designs for layers, generated content, tables, HiDPI/pixels, and DisplayList creation.
Announcements, etc
- Rust contribution ideas
- RustAlgebloat, a linear algebra library
- Table of Potential Closure Types
- rust-ci updates, categorization and documentation uploading

--- title: "Grading with tidyr" date: 2018-05-17T16:04:23-07:00 draft: true ---
It’s that time of year… The end of the semester means grading galore for professors and graduate student instructors. In this post, I will explore tidyr in the context of organizing and calculating grades.
I have some familiarity with reshape2, but I always have to Google an example to remember how to go from wide to long format and vice versa. I’m hoping the tidyr functions will be more intuitive, so I won’t end up like:
require(tidyr)
require(dplyr)
require(ggplot2)
I’ve generated some fake grade data based on the format that grades come in when you are an instructor at Berkeley (we use bCourses, similar to Moodle, Canvas, etc.).
setwd("~/Desktop")
grades=read.csv("gradesFake.csv")
Each row is a student. Each column is an assignment. The value in this table is the number of points earned.
head(grades,2)
## Student A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 A11 A12 A13 A14 A15 A16 A17
## 1 A 1 0.5 0.5 1 1.0 1 1 1 1 2 3 2 3 2 2 2 2
## 2 B 1 1.0 1.0 1 0.5 1 1 1 2 3 3 3 3 3 2 2 3
## A18 A19 A20 A21 A22 A23
## 1 1.0 1 1.0 1 1 0.5
## 2 0.5 1 0.5 1 1 1.0
gather
: use when your column names are actually levels of a particular variableIn the gather
syntax, the first element (after piping in the dataframe) is the new key (the name of the new variable we want, refers to what the current column names are) and the second element is the value (associated with the key, refers to what values are currently in each column). The next arguments are the columns that are going to be turned into key-value pairs. By using the minus sign we can say we want to reshape every column except student.
gathered.grades=grades %>% gather(assignment,grade,-Student)
head(gathered.grades,2)
## Student assignment grade
## 1 A A1 1
## 2 B A1 1
This gathered format allows us to easily group by student or assignment and see how things are going. Is a particular student struggling? Is there an assignment that everyone is stuggling with?
Note: This example is oversimplifying things since we haven’t yet said how many points each assignment is worth, but we’ll get there.
gathered.grades %>% group_by(Student) %>% summarise(meanPoints=mean(grade),sdPoints=sd(grade))%>% head(2)
## # A tibble: 2 x 3
## Student meanPoints sdPoints
## <chr> <dbl> <dbl>
## 1 A 1.37 0.726
## 2 B 1.59 0.949
gathered.grades %>% group_by(assignment) %>% summarise(meanPoints=mean(grade),sdPoints=sd(grade))%>% head(2)
## # A tibble: 2 x 3
## assignment meanPoints sdPoints
## <chr> <dbl> <dbl>
## 1 A1 0.933 0.258
## 2 A10 2.47 0.516
spread
: use when you want the levels of a variable to be separate columnsWe can undo gather
by using spread
. We may want to look at this shape if we want to see by assignment, how each student does.
 What if our assignment names also included the due date? We may want to be able to calculate the average grade per month of the semester to assess pacing.
grades2=grades

gathered.grades.dueDates=gathered.grades2 %>% separate(assignment,c("assignment","year","month","day"))
head(gathered.grades.dueDates,2)
## Student assignment year month day grade
## 1 A A1 2018 02 01 1
## 2 B A1 2018 02 01 1
There is not a lot to go on here, but we could imagine breaking things down by week instead of month to get a better sense.
gathered.grades.dueDates=gathered.grades %>% group_by(assignment)%>%summarise(maxPoss=max(grade)) %>%inner_join(gathered.grades.dueDates,by=c("assignment"="assignment"))
gathered.grades.dueDates %>% group_by(month)%>% summarise(avgGrade=mean(grade/maxPoss))
## # A tibble: 4 x 2
## month avgGrade
## <chr> <dbl>
## 1 02 0.883
## 2 03 0.871
## 3 04 0.917
## 4 05 0.800
We could do something similar with str_split
but it would take many more lines of code.
unite
: use when you want to concatenate multiple variables into oneTo undo separate
, we use unite
. We want to collapse all but Student and grade into a variable called assignment. I would usually use paste
.
gathered.grades.dueDates %>%unite(assignment,-Student, -grade,sep="-") %>% head(2)
## # A tibble: 2 x 3
## assignment Student grade
## <chr> <chr> <dbl>
## 1 A1-1-2018-02-01 A 1.
## 2 A1-1-2018-02-01 B 1.
replace_NA
: use to replace missing values with a particular valueWe may want to replace assignments that are missing with zeros. replace_na
requires a named list of what to replace an NA with in each column. Since we have many assignment columns, I had to ask Stack Overflow for some assistance.
## this seems like a prime candidate for walk from purrr, to be continued...
grades[1,sample(1:(ncol(grades)-1),1)]=NA
grades[5,sample(1:(ncol(grades)-1),1)]=NA
grades[10,sample(1:(ncol(grades)-1),1)]=NA

## 2 0.5 1 0.5 1 1 1.0
drop_na
: use when you want to remove rows with missing values in certain columnsdrop_na
may be useful when we want to drop each student’s lowest grade in a certain category of grades. Assuming all other NA values are converted to zeros…
gathered.grades.cat=gathered.grades %>% mutate(category=sample(1:3,nrow(gathered.grades),replace=T))
byStudent=split(gathered.grades.cat,pull(gathered.grades.cat,Student))
dropLowestScore=function(studentGrades,categoryToDrop){
catToDrop=studentGrades %>% filter(category==categoryToDrop)
toDrop=which.min(pull(catToDrop,grade))
studentGrades$grade[toDrop]=NA
## I don't think I can use pull here
studentGradesAdj=studentGrades %>% drop_na()
return(studentGradesAdj)
}
adjustedGrades=do.call("rbind",lapply(byStudent,dropLowestScore,1))
length(unique(pull(adjustedGrades,assignment)))
## [1] 23
adjustedGrades%>%group_by(Student)%>% summarise(count=n())%>%head(2)
## # A tibble: 2 x 2
## Student count
## <chr> <int>
## 1 A 22
## 2 B 22
complete
: use when you want to make implicit missing data explicitI often use expand.grid
and then merge
to do this. This is much more concise.
Note: If we only want to include levels of a variable that are present in the data we use nesting
to denote this within the complete
call.
dim(adjustedGrades)
## [1] 330 4
gathered.grades.cat%>%complete(Student,assignment)%>% dim
## [1] 345 4
separate_rows
: use when a value contains more than one piece of information and you want separate rows for each piece of informationNow suppose our spreadsheet of grades contains the maximum points possible for each assignment.  This call makes every row a combination of assignment and grade level. The last column is a list of all the students who received that particular grade on the assignment.
byAssignmentGrade=gathered.grades%>%nest(Student)
head(byAssignmentGrade)

That covers most of the tidyr verbs. I suspect that I will still need to look up examples to remember how to use gather
and spread
, but I’m hoping this cheat sheet will help me remember when to use which without having to try both on a sample data set.
The other verbs that I can see myself using frequently are complete
and spread
. I’m doing a project now where I use the expand.grid
and merge
trick way too often. I suspect it is a lot slower than complete
, so I’m going to make this switch and see if it speeds things up.
P.S. Just for the record: before posting this I searched for the dollar sign and rewrote the lines that involved it. Working on that guilty pleasure…
Happy Grading!


This project talks about Data Wrangling that involves three distinct
steps that can be revisited anytime; i.e. it is iterative if your
needs are not met. The three steps are:
Gathering
Assessing
Cleaning
Challenges
The following were the issues that I had to over come.
Gathering
Querying the API was bit troublesome as on an average it took about 30
minutes to fetch data.
Querying the API for missing records: I thought that there was
something wrong with my code, so I redid the entire thing, only to find out that the records had been deleted and
there was nothing wrong with the code.
Assessing
This was easy, it took about an hour or so find faults and criticise
it for all the mess it was in.
Although, assessing the image-predictions.tsv file was a bit
overwhelming as there was nothing wrong in it, until programmatic assessment
was done.
Cleaning
Well, this was the longest of all the processes. Defining the
cleaning goals initially was tough, but it all got easy after two
attempts.
Another challenge that I had to encounter was defining the regular
expressions for extracting name from text, and to find those, that
were missed by regexs'.

An impulse is defined as both a force multiplied by time (FΔt) and a change in momentum (Δp). The longer a force is applied, the more the momentum will change.
Examples of impulse:cars crashing
rockets accelerating
punching
jumping
derivation of impulse
$$a = \color{#f00}\frac{\Delta v}{\Delta t}$$$$F = ma$$ $$F = m \color{#f00}\frac{\Delta v}{\Delta t}$$ $$F \Delta t = m \Delta v$$
$$F \Delta t = m(v_f - v_i)$$ $$F \Delta t = mv_f - mv_i$$ $$F \Delta t = p_f - p_i$$ $$F \Delta t = \Delta p$$
$$J = \Delta p$$ $$F \Delta t = \Delta p $$
\(J\) = impulse [Ns, kg m/s] vector\(F\) = force [N, kg m/s²] vector
\(\Delta t\) = time period [s]
\(\Delta p\) = change in momentum [kg m/s] vector
\(m\) = mass [kg]
\(v\) = velocity[m/s] vector
When using impulse in solving problems you might want to unpack momentum into mass and velocity.
$$F \Delta t = m\Delta v$$ $$F \Delta t = mv - mu$$solution
Doubling force or time applied will produce the same increase in velocity. This is because F and Δt are in the same position in the equation.
$$\Delta v = \frac{\color{blue}F \Delta t}{m} $$solution
$$F \Delta t = m\Delta v$$ $$\frac{F \Delta t}{\Delta v} = m$$ $$\frac{(-100)(0.1)}{14-15} = m$$ $$\frac{(-100)(0.1)}{-1} = m$$ $$10 \, \mathrm{kg} = m$$solution
$$ 60 \left( \mathrm{ \frac{\color{red}{mile}}{\color{blue}{hour}}} \right)\left(\frac{1609\,\mathrm{ m}}{1 \,\color{red}{\mathrm{mile} }}\right)\left(\frac{1\, \color{blue}{ \mathrm{hour} }}{3600\, \mathrm{s} }\right) = 26.8 \mathrm{\tfrac{m}{s}} $$$$F \Delta t = m\Delta v$$ $$F = \frac{m\Delta v}{\Delta t}$$ $$F = \frac{(2250)(26.8)}{2.8}$$ $$F = \frac{60300}{2.8}$$ $$F = 21536 \, \mathrm{N}$$
How does the 0 to 60 miles/hour acceleration compare to the acceleration of gravity?
solution
$$F = 21536 N$$ $$F = ma$$ $$\frac{F}{m}=a$$ $$\frac{21536}{2250}=a$$ $$a = 9.57 \,\mathrm{ \tfrac{m}{s^2} }$$It's just a bit under the acceleration of gravity. How would that feel?
$$ g = 9.81 \, \mathrm{\tfrac{m}{s^2}} $$mass = kg
The graph above is velocity vs. time for a car collision. The slope of this graph is acceleration, and a high acceleration makes collisions dangerous.
Example: Based on this graph, what types of vehicles will be safer in collisions?solution
A vehicle with more mass will experience less acceleration. A plane, train or bus would be safe choices. On the other hand, a larger vehicle is safer for you, but more dangerous for whatever you crash into.
Another way to improve safety is to reduce the force. This can be done by increasing the total time for the collision. Like hitting a pillow instead of a brick. Modern cars lengthen the time of a collision with crumple zones.

| Source: | Phantomαs Web Designer is on GitHub |
Phantomαs Web Designer is a graphical interface for creation and edition of phantoms to be used in Phantomαs (link to Phantomαs' homepage).
Contents
Phantomαs Web Designer was tested on Mozilla Firefox. Although, it is fully compatible with any modern internet navigator.
No extra software is needed.
Using this app you will be able to
- Load or create from scratch any phantom model and save it as a JSON Phantomαs file
- Visualize any phantom model and its structure and components individually in a lightweight, three-dimensional and fully interactive interface.
- Add and remove fibers and isotropic regions in the phantom.
- Change the position and the radius for any isotropic region
- Edit the radius and the tangents' method for any fiber
- Add, remove and edit the position of any control point in a fiber
A fiber bundle in Phantomαs is defined as a cylindrical tube wrapped around its centerline. The centerline itself is a continuous curve in 3D, and can be simply created from a few control points.
This app uses the same specifications as Phantomαs. More information may be found in its documentation.
Phantomαs Web Designer divides the window in three panels:
The largest panel displays the current phantom layout. At start, view is from plane XY.
You may click to rotate, right-click to pan and use the mouse wheel to zoom. The view may be restored at any time by using the right panel camera placements.
To identify and view the structure of individual phantom elements, you may use the left panel element navigator.
The left panel allows you to navigate between the different phantom elements. You may also edit those, or add and remove.
To identify the different elements you may place your mouse over the selector lists. Those will highlight while mouse is placed onto their selection option. Highlighting elements for identifying will not affect the current task.
When clicking onto an option, edition options will pop up and the element will stay highlighted. To exit edition mode, select the *none* option or press Esc. Changes are saved once those take place.
To remove an element, you must access its edition mode.
Numeral inputs allow keyboard input, although it is restricted to valid values and a 1-decimal precision by default.
The editable elements in a region concern:
- Its name
- Its color
- Its radius
- Its position (x y z)
Name and color are editable from the title fields. Click to the square representing the color for deploying color editing interface.
Drag and Drop interactive controls for editing the position of the isotropic region can be deployed by clicking the button under the position fields. When drag and drop controls are active it stays yellow (as shown in the picture) and it can be turned off at any moment by clicking over again.
When entering fiber edition mode, its structure will feature in the scene.
The editable elements in a fiber concern:
- Its name
- Its color
- Its radius
- Its tangent-computing mode:
- Symmetric
- Incoming
- Outgoing
Name and color are editable from the title fields. Click to the square representing the color for deploying color editing interface.
A selection list for the fibers' control points is available at the bottom. Hovering those will also highglight them in the scene to help identifying.
Clicking over a control point in the list will pop up control point edition mode.
Only position may be edited.
While editing and navigating through control points, those may adopt four different colors in the scene:
- Yellow: Control points the user is not interacting with.
- Blue: For the control point being hovered in selection list.
- Red: Currently being edited control point.
- Green: Position changed control point that may be saved.
A control point is saved whenever its edition is quitted. When position was changed, the former version is on the scene in red color while the one to be saved is in green. The former may be recovered by pressing the Undo button, marked with an arrow.
Position may be edited manually by using the given fields. As well, by clicking on the Drag and Drop button, marked with a pointer. This option will allow an interactive edition in the scene itself.
The interactive edition allows different liberty grades:
- Axes, by using the arrows shown.
- Planes, by dragging the planes formed between the arrows.
- The screen plane, by clicking directly on the point.
New CP button creates a new control point. It is to be placed in the mid-point between the current and the next one. Remove CP removes the current control point after asking for confirmation.
Remove CP option is not available in first and last control points.
Right panel concerns everything regarding the visualization.
Options are:
- Preview Switch: Only available in editing mode. Allows the user to preview the phantom with any fade. Does not affect the edition. Unactive in the screenshot above.
- Skeleton Swith: When activated, the whole skeleton structure for the phantom is shown at all times. Unactive in the screenshot above.
- Axes Switch: Shows and hides the coordinates axis. Active in the screenshot above. Each axis features a different color:
- Red for X
- Green for Y
- Blue for Z
- Position: Move the scene to XY, XZ or ZY plane.
- Opacity: Select [0 - 50%] the opacity of the faded elements.
At bottom-right corner the export button allows you, at any moment, to download the JSON file for the current phantom.
The file is compatible with Phantomαs and may be loaded as well in Phantomαs Web Designer for further edition.
Keyboard shortcuts are available for most commonly used functions:
| Esc | Exit current edit |
| P | Switch preview mode |
| W | Switch skeleton structure |
| D | Switch drag and drop controls |
| A | Switch axes |
| X | Move to X=0 plane |
| Y | Move to Y=0 plane |
| Z | Move to Z=0 plane |
| S | Save phantom |
| U | Undo control point edition |
| Del | Remove current element |
Phantomαs Web Designer is open source and may be downloaded and forked on GitHub. Pull Requests are welcome!

This article describes an old version of Shadow DOM (v0). If you're interested in using Shadow DOM, check out our new article at developers.google.com, "Shadow DOM v1: self-contained web components". It covers everything in the newer Shadow DOM v1 spec shipping in Chrome 53, Opera, and Safari 10.
Web Components is a set of cutting edge standards that:
Does this mean you have to decide when to use HTML/JavaScript, and when to use Web Components? No! HTML and JavaScript can make interactive visual stuff. Widgets are interactive visual stuff. It makes sense to leverage your HTML and JavaScript skills when developing a widget. The Web Components standards are designed to help you do that.
It doesn’t make sense to have to switch to a different technology to
build a widget. For example, I’m definitely not a fan of making your
widget out of a <canvas>
. It is reliable — pages
won’t break if you change what it paints — but it’s hostile to
accessibility, indexing, composition, and resolution independence.
But there is a fundamental problem that makes widgets built out of HTML and JavaScript hard to use: The DOM tree inside a widget isn’t encapsulated from the rest of the page. This lack of encapsulation means your document stylesheet might accidentally apply to parts inside the widget; your JavaScript might accidentally modify parts inside the widget; your IDs might overlap with IDs inside the widget; and so on.
A particularly pernicious aspect of the lack of encapsulation is that if you upgrade the library and the internal details of the widget’s DOM changes, your styles and scripts might break in unpredictable ways.
Web Components is comprised of four parts:
Shadow DOM addresses the DOM tree encapsulation problem. The four parts of Web Components are designed to work together, but you can also pick and choose which parts of Web Components to use. This tutorial shows you how to use Shadow DOM.
Note: Shadow DOM is now available in Chrome 35+.
With Shadow DOM, elements can get a new kind of node associated with them. This new kind of node is called a shadow root. An element that has a shadow root associated with it is called a shadow host. The content of a shadow host isn’t rendered; the content of the shadow root is rendered instead.
For example, if you had markup like this:
<button>Hello, world!</button>
then instead of
your page looks like
Not only that, if JavaScript on the page asks what the button’s textContent is, it isn’t going to get “こんにちは、影の世界!”, but “Hello, world!” because the DOM subtree under the shadow root is encapsulated.
Now we'll look at using Shadow DOM to separate content from presentation. Let's say we have this name tag:
Here is the markup. This is what you’d write today. It doesn’t use Shadow DOM:

 Hi! My name is

 Bob

Because the DOM tree lacks encapsulation, the entire structure of the name tag is exposed to the document. If other elements on the page accidentally use the same class names for styling or scripting, we're gonna have a bad time.
We can avoid having a bad time.
Semantically we probably only care that:
First, we write markup that is closer to the true semantics we want:

Bob

Then we put all of the styles and divs used for presentation into
a <template>
element:

Bob

<template id="nameTagTemplate">

Hi! My name is

Bob

</template>
At this point ‘Bob’ is the only thing that is rendered. Because we
moved the presentational DOM elements inside
a <template>
element, they aren’t rendered, but
they can be accessed from JavaScript. We do that now to
populate the shadow root:

Templates, like Shadow DOM, are an emerging standard. The<template>
element is available in many modern browsers. You can also populate a shadow root using familiar properties and methods like innerHTML, appendChild, getElementById, and so on. This article is focused on Shadow DOM, so we won’t go further into how the template element works here. If you want to learn more about<template>
, see HTML's New Template Tag.
Now that we have set up a shadow root, the name tag is rendered again. If you were to right-click on the name tag and inspect the element you see that it is sweet, semantic markup:

Bob

This demonstrates that, by using Shadow DOM, we have hidden the presentation details of the name tag from the document. The presentation details are encapsulated in the Shadow DOM.
Our name tag now hides presentation details from the page, but it doesn’t actually separate presentation from content, because although the content (the name “Bob”) is in the page, the name that is rendered is the one we copied into the shadow root. If we want to change the name on the name tag, we’d need to do it in two places, and they might get out of sync.
HTML elements are compositional — you can put a button inside a table, for example. Composition is what we need here: The name tag must be a composition of the red background, the “Hi!” text, and the content that is on the name tag.
You, the component author, define how composition works with your
widget using a new element called <content>
. This
creates an insertion point in the presentation of the widget, and the
insertion point cherry-picks content from the shadow host to present
at that point.
If we change the markup in the Shadow DOM to this:
<template id="nameTagTemplate">

 Hi! My name is

 <content></content>

 </template>
When the name tag is rendered, the content of the shadow host is
projected into the spot that the <content>
element
appears.
Now the structure of the document is simpler because the name is only in one place — the document. If your page ever needs to update the user’s name, you just write:
document.querySelector('#nameTag').textContent = 'Shellie';
and that is it. The rendering of the name tag is automatically updated
by the browser, because we're projecting the content of the
name tag into place with <content>
.
Here is a live example using Shadow DOM:
Now we have achieved separation of content and presentation. The content is in the document; the presentation is in the Shadow DOM. They are automatically kept in sync by the browser when it comes time to render something.
By separating content and presentation, we can simplify the
code that manipulates the content — in the name tag example, that
code only needs to deal with a simple structure containing
one

instead of several.
Now if we change our presentation, we don't need to change any of the code!
For example, say we want to localize our name tag. It is still a name tag, so the semantic content in the document doesn’t change:

Bob

The shadow root setup code stays the same. Just what gets put in the shadow root changes:
<template id="nameTagTemplate">

 <content></content>
 と申します。
 </template>
Now we've got a Japanese name tag:
Background image by Mike Dowman, reused under Creative Commons license.
This is a big improvement over the situation on the web today, because your name update code can depend on the structure of the component which is simple and consistent. Your name update code doesn’t need to know the structure used for rendering. If we consider what is rendered, the name appears second in English (after “Hi! My name is”), but first in Japanese (before “と申します”). That distinction is semantically meaningless from the point of view of updating the name that is being displayed, so the name update code doesn’t have to know about that detail.
In the above example, the <content>
element
cherry-picks all of the content from the shadow host. By using the
select attribute, you can control what
a content element projects. You can also use multiple content
elements.
For example, if you have a document which contains this:

Bob

B. Love

bob@

and a shadow root which uses CSS selectors to select specific content:

 <content select=".first"></content>

 <content select="div"></content>

 <content select=".email"></content>

Note: select can only
select elements which are immediate children of the host node. That is, you
cannot select descendants (e.g.select="table tr"
).
The

element is matched by both
the <content select="div">
and <content
select=".email">
elements. How many times does Bob’s email
address appear, and in what colors?
The answer is that Bob’s email address appears once, and it is yellow.
The reason is that, as people who hack on Shadow DOM know, constructing the tree of what is actually rendered on screen is like a huge party. The content element is the invitation that lets content from the document into the backstage Shadow DOM rendering party. These invitations are delivered in order; who gets an invitation depends on to whom it is addressed (that is, the select attribute.) Content, once invited, always accepts the invitation (who wouldn’t?!) and off it goes. If a subsequent invitation is sent to that address again, well, nobody is home, and it doesn’t come to your party.
In the above example,

matches
both the div
selector and the .email
selector, but because the content element with the div
selector comes earlier in the document,

goes to the yellow party, and
nobody is available to come to the blue party. (That might
be why it is so blue, although misery loves company, so you
never know.)
If something is invited to no parties, then it doesn’t get rendered at all. That is what happened to the “Hello, world” text in the very first example. This is useful when you want to achieve a radically different rendering: Write the semantic model in the document, which is what is accessible to scripts in the page, but hide it for rendering purposes and connect it to a really different rendering model in Shadow DOM using JavaScript.
For example, HTML has a nice date picker. If you write <input
type="date">
you get a neat pop-up calendar. But what if you
want to let the user pick a range of dates for their dessert
island vacation (you know… with hammocks made out of Red Vines.) You
set up your document this way:

 Start: <input type="date" name="startDate" id="start">
 End: <input type="date" name="endDate" id="end">

but create Shadow DOM that uses a table to create a slick calendar which highlights the range of dates and so on. When the user clicks on the days in the calendar, the component updates the state in the startDate and endDate inputs; when the user submits the form, the values from those input elements get submitted.
Why did I include labels in the document if they’re not going to be rendered? The reason is that if a user views the form with a browser that doesn’t support Shadow DOM, the form is still usable, just not as pretty. The user sees something like:
Those are the basics of Shadow DOM — you pass Shadow DOM 101! You can do more with Shadow DOM, for example, you can use multiple shadow on one shadow host, or nested shadows for encapsulation, or architect your page using Model-Driven Views (MDV) and Shadow DOM. And Web Components are more than just Shadow DOM.
We explain those in later posts. Now, follow Web Components on Google+.

This page hosts only the LaTeX predictor system, which is the essence of this project.
This system allows takes an input image from the user, then it will display the Segmentation, Classification and Parsing steps, and then finally it will output the result of the Parsing step in LaTeX form.
The result LaTeX can be forwarded then to the Compiler to check if the prediction was correct or not.
This page takes input in LaTeX form and compile it into an image.
This can be helpful for compiling images to test the predictor and for checking the accuracy of the predictor manually.
Extra features included in this page:
Using the Compiler page and Predictor page for testing can be a bit tedious, we need to compile the images, and then put them manually in the Predictor page to test the predictor.
For that case, we made the Tester page, which merges these two pages together. This page receive LaTeX input, compile it, feed it through the predictor, and give us the results back in LaTeX form. It also displays the Segmentation, Classification and Parsing steps similar to the Predictor page.
This page also have the same extra features as the Compiler page.
These are variables that can be put in the LaTeX input in the Compiler page or Tester page to produce different result on each compilation attempt.
These random variables are originally used by the backend for automatic dataset generation, which is used for system testing, but we used the API in the front-end here to let users test it.
An example of using the random variables is "1 + {{ "{{num1}}" }}
". This example will be
compiled to 1 +
a random number, this random number is in range of -999
to
999
. So we might get the result of 1 + 876
for example.
The user can use up to 5 variables for each variable type (from 1 to 5), and the same variable
will share the content
in every occurrence. For example "{{ "{{num1}} + {{num1}}" }}
" will generate random numbers
for num1
, but it will be the same in both occurrences, for example it might result in
124 + 124
or 777 + 777
.

George Washington (February 22, 1732 - December 14, 1799) was the first President of the United States (1789), the Commander-in-Chief of the Continental Army during the American Revolutionary War, and one of the Founding Fathers of the United States. He presided over the convention that drafted the current United States Constitution and during his lifetime was called the "father of his country". Widely admired for his strong leadership qualities, Washington was unanimously elected president by the Electoral College in the first two national elections. He oversaw the creation of a strong, well-financed national government that maintained neutrality in the French Revolutionary Wars, suppressed the Whiskey Rebellion, and won acceptance among Americans of all types. Washington's incumbency established many precedents, still in use today, such as the cabinet system, the inaugural address, and the title Mr. President.

Have you tried using any of the insight and techniques for growing trust and sincerity? How did it go?
When I was training people at McDonald's, I would always make an effort to connect with them on an empathetic-level. I found that after being courteous to them, or standing up for them -- as well as facilitating their learning -- they begun to trust me more than the manager's (lmao). Often I'd get new crew come to me, as they were to intimidated or scared to ask management -- which I saw as a product of compassion.
Try empathic listening - how did it go?
To draw on from the last question... you'd often be required to listen to what new crew were experiencing; being able to
reflect and speak back to them, in a way which mirrored what they were feeling was a good way to
connect and build trust.
I think in general, without the construct of an "exercise", people are often too scared to say what
they are feeling, in fear they may get shot-down, or "deflected". I feel personally, that empathic
listening can go a long way in helping reassure someone, or help them (even marginally).
How did you find the loving kindness meditation?
I felt it was a great way to feel and build empathy, especially towards someone you care about. It's a way of understanding that regardless of what you may be feeling now -- or have felt in the past -- that this person has likely had similar experiences.
Complete the political awareness exercise here in writing.
Think of a difficult situation from your present or past, when there was some conflict or disagreement,
something real, something that has some meaning and potency for you.
Keeping it related to my time at McDonald's lol, there was a situation where I offered to remedy
a customer's issue with free stuff! To me, the issue that the customer had was relatively minor --
i.e., it was being blown out of proportion, but I realised that there's no point in trying to argue,
as it would only slow service down (and probably anger the customer more).
When the manager on floor realised I had given away something for free (trying to do something courteous
/ nice), they were immediately angry and threatened me.
To me, I was only trying to be courteous, and if it appeases both parties involved then it is a
good result. After explaining my decision-making to the manager afterwards, she apologised and agreed
that she could see where I was coming from.
Conversely, I could see where she was coming from; being more concerned about the long-term benefits
of giving stuff away.

New Uno deck promises to keep families away from politics
Card game removes red, blue cards
by Mallory Hughes, CNNEL SEGUNDO, Calif. - Please pass the turkey but hold the politics.
Mattel's limited-edition Nonpartisan Uno deck is out just in time to keep Thanksgiving dinner politics-free.
The new version removes the red and blue cards -- which could be seen as politically charged -- and introduces a new VETO card to help families everywhere keep the peace.
On the pack, it says "No red or blue cards means no taking sides!"
One survey by the American Psychological Association found 38% of respondents saying their stress levels increase during the holidays, in part because of family gatherings.
Sure, political discussions are important. But is Thanksgiving really the time? Let's keep the debate around pumpkin or pecan pie. (The correct answer is both.)
If -- no, when a family member breaks the "no politics" rule -- just VETO them!
During an Uno game, the new VETO card skips that player's next turn and makes them change the subject. But it might be smart to keep that card in your pocket at the dinner table, too.
The classic red and blue cards were replaced with more politically neutral colors of orange and purple. The new packaging is purple as well; being an intermediate color formed of red and blue, it should encourage people to find some common ground.
And if all that doesn't work, just make them Draw Four.
The Uno Nonpartisan can be found at Walmart stores for $5.99.


You may soon be able to run Windows 10 IoT Core on a Calculator
by RakaWindows 10 IoT Core is for the smallest embedded systems like washing machine, automatic door lock, and of course, the Rasberry Pi, which is popularly known as the “The credit-card-sized computer.”
But aside from Rasberry Pi, you might soon be able to run Windows Core IoT Core on your Calculator. A developer(known as @imbushuo on Twitter) seems to have managed to successfully install Windows 10 IoT Core on an HP Prime Graphing Calculator.
However, there is still a lot of work to be done as the project is not completed yet. That said, we still don’t know he managed to install Windows 10 IoT Core on the HP Prime Graphing Calculator. The developer is expected to share more details about the project in the coming days.


Situated to the east of Beachy Head, Eastbourne sits on the Sussex coast where the White Cliffs have given way to the lower, sandier coastline.
The only shelter here, like Brighton, is in the marina, but unlike Brighton, it is cut back into the land. No anchoring permitted in this artificial harbour.
The entrance can be unsafe in strong SE/NE winds and if in doubt call the Harbour Master before entry. In winds about F5 it is best to time arrival within an hour and a half of high water. The entrance is dredged, but if your draft is over 2 metres and it is close to low water, it is advisable to call to check the depth.

William is a post-bacc student living in Hawai'i
Working with Brian this summer on studying emoji use in the /r/WallStreetBets community
🚀🚀🚀 Welcome William! 🚀🚀🚀
Quick intro for William 👋
🌹: Successes, wins, positive developments!
🌱: Promising, new ideas, potential developments
🌵: Challenges, setbacks, need support
This is a Reveal.js deck hosted on a GitHub Page
What's Reveal.js? 📜
What's GitHub Pages? 🌐
What's GitHub? 📁
Let's go in reverse!
(Yes, I can hear your 🙄😒🤢 through Zoom)
GitHub is an important platform for open science and collaboration
We shouldn't use it for everything, but we shouldn't be scared of it either!
Host simple-to-moderately complex websites using GitHub Pages!
Git is a version control system for tracking changes
GitHub is a social coding platform using Git but also supporting collaborations
Not just hosting code and archives, but also documentation, bug reports, wikis, and more
A repository ("repo") is project-level collection of files
Users "push" ⬆ and "pull" ⬇ changes to the project
Copy ("fork" 🍴) any repo to make your own changes
Collisions may require merging or reverting ⁉
Individual 👩💻 + organizations 🏢 + projects 👪
If you haven't already, create a GitHub account! 🐤
This will likely follow you the rest of your career! 🔪
Your account hosts its own repos
Also documents your contributions over time 📈
An important part of technical recruiting! 💰
Shared accounts that can host their own repos
COLUMN's GitHub org is here
I invited who I could find, but send me your account if you haven't created one yet so I can add you 📨
Arcadia is already hosting her dissertation code! 💃
Most tutorials use GitHub from the command line
I still use easy-mode GUI: GitHub Desktop
Click the green "Code" button in upper-left of any repo to "clone" the code to your computer
Many things can also be done from the web GUI
You can also use GitHub to host websites! (Docs)
HTML/CSS/JS are frustrating but important skills to develop or keep sharp! 🦖
Consider this as an inexpensive option for hosting your own personal website and portfolio
We could also do interesting things with our lab web presence!
In the Settings for a repo, go to "Pages", and select the "main" branch under "Source"
Then you should be able to access the website at accountname.github.io/reponame/
Create a repository called accountname.github.io
to host a website
You'll need a index.html
as a landing page
Otherwise link directly into the HTML file
There's not much at https://columnlab.github.io/Meetings/
This presentation is an HTML file located at https://columnlab.github.io/Meetings/2021/2021-05-19-Group.html
Make the repo and enable the "Pages" option
Clone the repo to your local machine
Make/open an HTML file inside the repo directory
Save your HTML file, use GitHub Desktop to "commit to main", and then "push" to origin
Go to your account/org github.io page to see it!
It may take a minute or so for your changes to update on the page
My bad personal GitHub Page is: https://brianckeegan.github.io/
I host GitHub Pages with lectures using Reveal.js decks on the "cuinfoscience" org: https://cuinfoscience.github.io/INFO3402-Spring2021/
You can make really slick websites using Jekyll (docs)
Think of Jekyll Themes like WordPress themes!
Some non-trivial configuration and setup needed 🤔
I haven't ascended to this level, but would like to someday! 🙏
Check out the Demo
A web framework for interactive presentations
Won't replace PowerPoint for high-stakes presentations
But slick and lightweight way to share presentations!
The Reveal.js installation documentation recommends a "local hosting" setup
A local hosting setup requires you to maintain and serve the Reveal.js files yourself
Content Delivery Networks (CDNs) host data like videos and software instead of your server
In addition to laziness and simplicity, this has benefits for speed, consistency, and security
Download the Reveal.js example template
Open in Sublime and look for CSS and JS assets
Note they have a relative rather than absolute path
Replace these relative paths with links to CDN assets
CDNJS is popular CDN for hosting JavaScript libraries
Find the Reveal.js 4.1.0 library on CDNJS
Replace the relative href
paths with the CDN paths for each CSS and JS asset:
Inspect the entire example template file and replace all the CSS and JS assets with CDN links
.min.
means minified → condensed code
reveal.css
and reveal.js
are different files!
Follow the documentation
Each slide is a section
Appears last
Appears first
Appears second
What does this look like?
def addition(a,b):
sum = a + b
return sum
Reveal.js comes with 11 themes by default
These default themes are defined in standalone CSS files we get from the CDN
Swap out the default "black" theme file
for another on the list like "moon"
Add a data-notes
attribute within a section
tag
Write fancy equations to impress people!
\[ \tiny{ \text{similarity} = \cos(\theta) = {\mathbf{A} \cdot \mathbf{B} \over \|\mathbf{A}\| \|\mathbf{B}\|} = \frac{ \sum\limits_{i=1}^{n}{A_i B_i} }{ \sqrt{\sum\limits_{i=1}^{n}{A_i^2}} \sqrt{\sum\limits_{i=1}^{n}{B_i^2}} } } \](This LaTeX/MathJax syntax can be found on Wikipedia)
Reveal has some serious downsides
Discovered remark.js this morning
Mardown + supports good features + adds more features
That was a lot!
Everyone should get a personal website running before January 2022!
That could be GitHub Pages, or WordPress, or something else!
If you learn to do something cool on web, with Python, in LaTeX, etc.
Also start to think about what we want to do with using tools like GitHub, webpages, etc. to:
Wednesday, June 2 at 2pm MT
Skill share? Work-in-progress? Upcoming presentation?
Social get-together/social bucketlist before then?


Welcome to team Factory rejects's website. Over the course of the past 2 weeks we have surveyed now over 60 people and asked them about their take on questions pertaining to piracy, media, and paid media outlets.
Our survey was directed at social media users within a median age of 20 - 30 years of age. Suprisingly enough we yielded results that allowed us to make opinions based on a group of people.
Pleas note that this website does not support mobile format at this current time. Work is underway to remedy this problem.

Immutability(initialValue: T)
A property delegate to create thread safe immutable frozen properties backed by AtomicReference.
The property can be declared with by [Immutability] (initialValue)
keyword.
All get and set operations are then performed atomically.
Note that the values are immutable once set.
So any updates to the internal properties of the value will cause a failure.
This is really useful if you want an immutable object so that it can be shared among different threads with some dynamic behavior (like lazy initialization)
// Since top level objects are always immutable, they can be accessed from any thread.
object SharedObject{
val person: Person? by Immutability<Person?>(initialValue = null)
fun initialize(p: Person) { // any thread can now atomically update the person property.
person = p // will succeed
person.name = "" // will cause error
}
}
class MyClass {
val value: Int by Immutability<Int>(initialValue = 0)
}
// can be called from any thread as long as instance is thread shareable.
instance.value = 3

Who was this man?
Ivan Konstantinovich Aivazovsky (Russian: Иван Константинович Айвазовский; 29 July 1817 – 2 May 1900) was a Russian Romantic painter. Baptized as Hovhannes Aivazian, he was born into an Armenian family in the Black Sea port of Feodosia in Crimea and was mostly based there.
Following his education at the Imperial Academy of Arts in Saint Petersburg, Aivazovsky traveled to Europe and lived briefly in Italy in the early 1840s. He then returned to Russia and was appointed the main painter of the Russian Navy. Aivazovsky had close ties with the military and political elite of the Russian Empire and often attended military maneuvers. He was sponsored by the state and was well-regarded during his lifetime. The saying "worthy of Aivazovsky's brush", popularized by Anton Chekhov, was used in Russia for describing something lovely. He remains highly popular in Russia in the 21st century.
Aivazovsky was also popular outside Russia. He held numerous solo exhibitions in Europe and the United States. During his almost 60-year career, he created around 6,000 paintings, making him one of the most prolific artists of his time. The vast majority of his works are seascapes, but he often depicted battle scenes, Armenian themes, and portraiture. Most of Aivazovsky's works are kept in Russian, Ukrainian and Armenian museums as well as private collections.
Born a mortal, he left immortal memories.
His Legacy
During his 60-year career, Aivazovsky produced around 6,000
paintings of, what one online art magazine describes,
very different value ... there are masterpieces and there are
very timid works
. However, according to one count as many as 20,000 paintings are
attributed to him. The vast majority of Aivazovsky's works depict
the sea. He rarely drew dry-landscapes and created only a handful
of portraits. According to Rosa Newmarch Aivazovsky
never painted his pictures from nature, always from memory, and
far away from the seaboard.
Rogachevsky wrote that
His artistic memory was legendary. He was able to reproduce
what he had seen only for a very short time, without even
drawing preliminary sketches.
Bolton praised
his ability to convey the effect of moving water and of
reflected sun and moonlight.
He was the most influential seascape painter in nineteenth-century
Russian art. According to the Russian Museum,
he was the first and for a long time the only representative of
seascape painting
and
all other artists who painted seascapes were either his own
students or influenced by him.
Ivan Aivazovsky is one of the few Russian artists to achieve wide
recognition during his lifetime. Today, he is considered as one of
the most prominent marine artists of the 19th century, and,
overall, one of the greatest marine artists in Russia and the
world. Aivazovsky was also one of the few Russian artists to
become famous outside Russia. In 1898, Munsey's Magazine wrote
that Aivazovsky is
better known to the world at large than any other artist of his
nationality, with the exception of the sensational
Verestchagin
. However, according to art historian Janet Whitmore he is
relatively unknown in the west. Art historian Rosalind Polly
Blakesley noted in a 2003 book review that Aivazovsky has not been
incorporated into the mainstream Western history of art.
Aivazovsky's house in Feodosia, where he had founded an art museum in 1880, is open to this day as the Aivazovsky National Art Gallery. It remains a central attraction in the city and holds the world's largest collections (417) of Aivazovsky paintings. A statue of the artist stands in front.
Aivazovsky is - no matter who says what - a star of first magnitude, and not only in our country, but also in history of art in general.

The first time I had 5meo-dmt, I was at a festival last summer. It was a time in my life that I was going through massive emotional turmoil and subconscious self abuse. I have had many intense psychedelic experiences before but nothing like this.
I had been awake for about 4 days, had just bought some opium and took some to someone I respected on the scene. He loaded a fat pipe of it and passed it to me, he told me there was a bit of 5meo left in the pipe.
I took a large lung full and held it in for about 30 secs. I had what can only be described as the most intense, scary ordeal of my life. after experiencing about 2 minutes of intense rushing I started to to realise the trip was far too powerful and out of control.
After about 40secs I could feel my throat, heart and lungs shutting down and I thought I was gonna die, this created a sense of panic and anxiety which only served to amplify the bad experience . Eventually , I could not call for help, I managed to catch the guys attention who I was with and croaked for help.
All I remember was extreme fear and panic. I remember him performing some chanting or some sort of mantra with his hand on my chest and it managed to pull me out. It took me a good hour of smaller panicky rushes to calm down and some healing over the next few months to even allow me to think about the experience without panicking again.
Its about 6 months on and I'm slowly starting to feel comfortable to digest what has happened.
I am healing and maybe one day I will try it again but BE WARNED!!

Tough times ahead… GVT to Raise Passport Fees
by Sharon ChirisaTough times ahead… GVT to Raise Passport Fees
The registrar-general(RG)’s office has announced that it will hike up its fees in a bid to retain enough foreign currency needed to produce sufficient passports for Zimbabweans,
According to reports by the Daily News, the RG’s office is swamped with a staggering 386 000 passport backlog which has caused distress among Zimbabweans who wish to travel abroad for better opportunities.
Registrar-General Clemence Masango said the existing passport fees were not economical and needed an urgent review to reflect the current economic situation in the country.
He stated that material is imported and it requires foreign currency. Lately they have not been able to get as much foreign currency in order to avail passports according to demand.
