About me...
Hello! I am from Larkspur, California, a city in Marin County which is north of San Francisco.
My hobbies include playing basketball, running, and traveling.
I graduated from Duke University in 2013. I attended Marin Catholic High School.
Something quirky about me is my irrational fear of sharks. I love to swim and be in the ocean but I am convinced the entire time I am in the water that I am about to become the victim of a Jaws encounter. I attribute this to watching too many nature documentaries as a child.

Class that emits particles with customizable initial conditions.
This emitter is universal with respect to the initial conditions of each emitted particle. It works with callbacks that return initial values for the particle attributes (position, rotation, color, ...). So you can pass constants, random distributions, or any functions that compute the value in an arbitrary way. Have a look at the thor::Distributions namespace for useful predefined functions.

public final class WeekFields extends Object implements Serializable
A standard week is seven days long, but cultures have different definitions for some
other aspects of a week. This class represents the definition of the week, for the
purpose of providing TemporalField
instances.
WeekFields provides five fields,
dayOfWeek()
, weekOfMonth()
, weekOfYear()
,
weekOfWeekBasedYear()
, and weekBasedYear()
that provide access to the values from any temporal object.
The computations for day-of-week, week-of-month, and week-of-year are based on the proleptic-year, month-of-year, day-of-month, and ISO day-of-week which are based on the epoch-day and the chronology. The values may not be aligned with the year-of-Era depending on the Chronology.
A week is defined by:
| Date | Day-of-week | First day: Monday Minimal days: 4 | First day: Monday Minimal days: 5 |
|---|---|---|---|
| 2008-12-31 | Wednesday | Week 5 of December 2008 | Week 5 of December 2008 |
| 2009-01-01 | Thursday | Week 1 of January 2009 | Week 0 of January 2009 |
| 2009-01-04 | Sunday | Week 1 of January 2009 | Week 0 of January 2009 |
| 2009-01-05 | Monday | Week 2 of January 2009 | Week 1 of January 2009 |
week-of-week-based-year
and one for
week-based-year
. In a week-based-year, each week
belongs to only a single year. Week 1 of a year is the first week that
starts on the first day-of-week and has at least the minimum number of days.
The first and last weeks of a year may contain days from the
previous calendar year or next calendar year respectively.
| Date | Day-of-week | First day: Monday Minimal days: 4 | First day: Monday Minimal days: 5 |
|---|---|---|---|
| 2008-12-31 | Wednesday | Week 1 of 2009 | Week 53 of 2008 |

public static final WeekFields ISO
The ISO-8601 standard defines a calendar system based on weeks. It uses the week-based-year and week-of-week-based-year concepts to split up the passage of days instead of the standard year/month/day.
Note that the first week may start in the previous calendar year. Note also that the first few days of a calendar year may be in the week-based-year corresponding to the previous calendar year.
public static final WeekFields SUNDAY_START
Defined as starting on Sunday and with a minimum of 1 day in the month. This week definition is in use in the US and other European countries.
public static final TemporalUnit WEEK_BASED_YEARS
This allows a number of week-based-years to be added to, or subtracted from, a date.
The unit is equal to either 52 or 53 weeks.
The estimated duration of a week-based-year is the same as that of a standard ISO
year at 365.2425 Days
.
The rules for addition add the number of week-based-years to the existing value for the week-based-year field retaining the week-of-week-based-year and day-of-week, unless the week number it too large for the target year. In that case, the week is set to the last week of the year with the same day-of-week.
This unit is an immutable and thread-safe singleton.
public static WeekFields of(Locale locale)
WeekFields
appropriate for a locale.
This will look up appropriate values from the provider of localization data.
locale
- the locale to use, not nullpublic static WeekFields of(DayOfWeek firstDayOfWeek, int minimalDaysInFirstWeek)
WeekFields
from the first day-of-week and minimal days.
The first day-of-week defines the ISO DayOfWeek
that is day 1 of the week.
The minimal number of days in the first week defines how many days must be present
in a month or year, starting from the first day-of-week, before the week is counted
as the first week. A value of 1 will count the first day of the month or year as part
of the first week, whereas a value of 7 will require the whole seven days to be in
the new month or year.
WeekFields instances are singletons; for each unique combination
of firstDayOfWeek
and minimalDaysInFirstWeek
the
the same instance will be returned.
firstDayOfWeek
- the first day of the week, not nullminimalDaysInFirstWeek
- the minimal number of days in the first week, from 1 to 7IllegalArgumentException
- if the minimal days value is less than one
or greater than 7public DayOfWeek getFirstDayOfWeek()
The first day-of-week varies by culture.
For example, the US uses Sunday, while France and the ISO-8601 standard use Monday.
This method returns the first day using the standard DayOfWeek
enum.
public int getMinimalDaysInFirstWeek()
The number of days considered to define the first week of a month or year varies by culture. For example, the ISO-8601 requires 4 days (more than half a week) to be present before counting the first week.
public TemporalField dayOfWeek()
WeekFields
.
This is similar to ChronoField.DAY_OF_WEEK
but uses values for
the day-of-week based on this WeekFields
.
The days are numbered from 1 to 7 where the
first day-of-week
is assigned the value 1.
For example, if the first day-of-week is Sunday, then that will have the value 1, with other days ranging from Monday as 2 to Saturday as 7.
In the resolving phase of parsing, a localized day-of-week will be converted
to a standardized ChronoField
day-of-week.
The day-of-week must be in the valid range 1 to 7.
Other fields in this class build dates using the standardized day-of-week.
public TemporalField weekOfMonth()
WeekFields
.
This represents the concept of the count of weeks within the month where weeks
start on a fixed day-of-week, such as Monday.
This field is typically used with dayOfWeek()
.
Week one (1) is the week starting on the getFirstDayOfWeek()
where there are at least getMinimalDaysInFirstWeek()
days in the month.
Thus, week one may start up to minDays
days before the start of the month.
If the first week starts after the start of the month then the period before is week zero (0).
For example:
- if the 1st day of the month is a Monday, week one starts on the 1st and there is no week zero
- if the 2nd day of the month is a Monday, week one starts on the 2nd and the 1st is in week zero
- if the 4th day of the month is a Monday, week one starts on the 4th and the 1st to 3rd is in week zero
- if the 5th day of the month is a Monday, week two starts on the 5th and the 1st to 4th is in week one
This field can be used with any calendar system.
In the resolving phase of parsing, a date can be created from a year, week-of-month, month-of-year and day-of-week.
In strict mode, all four fields are validated against their range of valid values. The week-of-month field is validated to ensure that the resulting month is the month requested.
In smart mode, all four fields are validated against their range of valid values. The week-of-month field is validated from 0 to 6, meaning that the resulting date can be in a different month to that specified.
In lenient mode, the year and day-of-week are validated against the range of valid values. The resulting date is calculated equivalent to the following four stage approach. First, create a date on the first day of the first week of January in the requested year. Then take the month-of-year, subtract one, and add the amount in months to the date. Then take the week-of-month, subtract one, and add the amount in weeks to the date. Finally, adjust to the correct day-of-week within the localized week.
public TemporalField weekOfYear()
WeekFields
.
This represents the concept of the count of weeks within the year where weeks
start on a fixed day-of-week, such as Monday.
This field is typically used with dayOfWeek()
.
Week one(1) is the week starting on the getFirstDayOfWeek()
where there are at least getMinimalDaysInFirstWeek()
days in the year.
Thus, week one may start up to minDays
days before the start of the year.
If the first week starts after the start of the year then the period before is week zero (0).
For example:
- if the 1st day of the year is a Monday, week one starts on the 1st and there is no week zero
- if the 2nd day of the year is a Monday, week one starts on the 2nd and the 1st is in week zero
- if the 4th day of the year is a Monday, week one starts on the 4th and the 1st to 3rd is in week zero
- if the 5th day of the year is a Monday, week two starts on the 5th and the 1st to 4th is in week one
This field can be used with any calendar system.
In the resolving phase of parsing, a date can be created from a year, week-of-year and day-of-week.
In strict mode, all three fields are validated against their range of valid values. The week-of-year field is validated to ensure that the resulting year is the year requested.
In smart mode, all three fields are validated against their range of valid values. The week-of-year field is validated from 0 to 54, meaning that the resulting date can be in a different year to that specified.
In lenient mode, the year and day-of-week are validated against the range of valid values. The resulting date is calculated equivalent to the following three stage approach. First, create a date on the first day of the first week in the requested year. Then take the week-of-year, subtract one, and add the amount in weeks to the date. Finally, adjust to the correct day-of-week within the localized week.
public TemporalField weekOfWeekBasedYear()
WeekFields
.
This represents the concept of the count of weeks within the year where weeks
start on a fixed day-of-week, such as Monday and each week belongs to exactly one year.
This field is typically used with dayOfWeek()
and
weekBasedYear()
.
Week one(1) is the week starting on the getFirstDayOfWeek()
where there are at least getMinimalDaysInFirstWeek()
days in the year.
If the first week starts after the start of the year then the period before
is in the last week of the previous year.
For example:
- if the 1st day of the year is a Monday, week one starts on the 1st
- if the 2nd day of the year is a Monday, week one starts on the 2nd and
the 1st is in the last week of the previous year
- if the 4th day of the year is a Monday, week one starts on the 4th and
the 1st to 3rd is in the last week of the previous year
- if the 5th day of the year is a Monday, week two starts on the 5th and
the 1st to 4th is in week one
This field can be used with any calendar system.
In the resolving phase of parsing, a date can be created from a week-based-year, week-of-year and day-of-week.
In strict mode, all three fields are validated against their range of valid values. The week-of-year field is validated to ensure that the resulting week-based-year is the week-based-year requested.
In smart mode, all three fields are validated against their range of valid values. The week-of-week-based-year field is validated from 1 to 53, meaning that the resulting date can be in the following week-based-year to that specified.
In lenient mode, the year and day-of-week are validated against the range of valid values. The resulting date is calculated equivalent to the following three stage approach. First, create a date on the first day of the first week in the requested week-based-year. Then take the week-of-week-based-year, subtract one, and add the amount in weeks to the date. Finally, adjust to the correct day-of-week within the localized week.

USD/CHF stays offered below 0.9967 – Commerzbank
by Pablo PiovanoThe offered stance in USD/CHF is seen unchanged while below the 0.9967 level, noted Karen Jones, Team Head FICC Technical Analysis at Commerzbank.
Key Quotes
“USD/CHF remains offered while capped by the .9967 6 month downtrend and attention is on the .9844/41 September and October lows. Failure at the next lower .9799 September low would push key support at .9716/.9659 to the fore. This is the location of the January, June, mid- and late August lows. Below here sits the .9659 August low and the September 2018 low at .9543”.

Google Panics, Adds 10 More Games To Stadia's Launch Lineup
by Luke PlunkettPerhaps spooked by the fact the only people who seem to care about the impending launch of their Stadia home streaming platform are those noting everything wrong with it, Google has at the 11th hour — this thing is releasing tomorrow, on November 19! — almost doubled the number of games that’ll be available when it goes live.
Originally intending to launch with 12 games, Google will now be releasing 22, with the extra ten — including titles such as NBA 2K20, Final Fantasy XV and Rage 2 — having been bumped up from the list of titles that were originally expected to come to Stadia “later in 2019".
22 games is better than 12! Has it made you any more tempted to get a Stadia at launch? If so, let us know in the comments below and haha of course it hasn’t nobody asked for this thing.


This blog post introduces Lie Groups and defines important concepts that are needed for state estimation or SLAM. Largely adapted from "A Micro lie-theory for state estimation in Robotics"
Preliminaries
Manifold
A smooth manifold is a curved and differentiable hyper-surface – one with no spikes / edges – that locally resembles a linear space \(\mathbb{R}^n\) embedded in a higher dimensional space.
Examples:
3D Vectors \(\in \mathbb{R}^3\) with unit-norm constraint form the spherical manifold \(\mathbb{S}^3\)
Rotations in the 2D plane \(\in \mathbb{R}^2\) form a circular manifold
3D Rotations form a hypersphere (3-sphere) in \(\mathbb{R}^4\)
Figure 1: A manifold $$\mathcal{M}$$ and its associated tangent space $$ \mathcal{T}_\times \mathcal{M} (\mathbb{R}^2) $$ tangent at the point $$ \mathcal{X} $$ and a side view. The velocity element $$ \dot{\mathcal{X}} = \frac{\partial{X}}{\partial{t}} $$ does not belong to the manifold but to the tangent space.
Group
A Group \(\mathcal{G}\) is a set with a composition operator \(\circ\), that for elements \(X, Y, Z \in G\) satisfy the following axioms:
Closure under \(\circ\): \(X \circ Y \in \mathcal{G}\)
Identity \(E\): \(E \circ X = X \circ E = X \in \mathcal{G}\)
Inverse \(X^{-1}\): \(X^{-1} \circ X = X \circ X^{-1} = E \in \mathcal{G}\)
Associativity: \((X \circ Y) \circ Z = X \circ (Y \circ Z)\)
Notice the omission of commutativity
Lie Group
A smooth manifold that looks identical (example: A sphere, a circle) at every point and satisfies all group properties:
Composition of Lie group elements remain in the lie group
Each lie group has an identity element
Every element has an inverse.
Examples
The unit complex number group \(\mathbb{S}^1: z = \cos(\theta) + i \sin(\theta) = e^{i \theta}\) under complex multiplication as the composition operator is a Lie group. A Lie group element \(z \in \mathbb{S}^1\) rotates a regular complex vector \(\mathbf{x} = x + iy\) via complex multiplication to \(\mathbf{x}^\prime = \mathbf{z} \circ \mathbf{x}\). The unit norm constraint of the unit complex group defines a 1-sphere in 2D space.
Figure 1: A manifold $$\mathcal{M}$$ and its associated tangent space $$ \mathcal{T}_\times \mathcal{M} (\mathbb{R}^2) $$ tangent at the point $$ \mathcal{X} $$ and a side view. The velocity element $$ \dot{\mathcal{X}} = \frac{\partial{X}}{\partial{t}} $$ does not belong to the manifold but to the tangent space.

If checked, ZAProxy starts before all build steps (so, in a pre-build step). This allows to follow interactions of an user on a webapp and receive all responses from it. For example, you can start ZAProxy as a pre-build step, setup a Selenium build step that will navigate through a webapp. ZAProxy will capture events and after that, you can setup a ZAProxy build step to scan url found in Selenium step.
Be careful, the ZAProxy build step must be placed after the Selenium build step.

v0.2.0 has been released. Please look through the breaking changes in the changelog and upgrade your project.
To define routes for your server, use the get
, post
, put
(or patch
) and del
methods. Here’s an example:
// mirage/config.js
this.get('/authors', () => {
return ['Link', 'Zelda', 'Epona'];
});
Now when your Ember app makes a GET request to /authors
, it will receive this data.
Each verb method has the same signature. The first argument is the path (URL) and the second is the actual function handler that returns the response:
this.verb( path, handler )
Here are some more examples:
this.get('/users/current', () => {
return {
name: 'Zelda',
email<EMAIL_ADDRESS>};
});
this.get('/events', () => {
let events = [];
for (let i = 1; i < 1000; i++) {
events.push({ id: i, value: Math.random()});
};
return events;
});
In the examples above, we wrote the response data directly in the route. Instead of doing this, Mirage provides a simple in-memory database you can use to make your routes more versatile.
In previous versions of Mirage, you interacted with the database directly in your route handlers. Models were introduced as a wrapper around the database to provide better means for dealing with associations and formatting responses, which we’ll get to shortly.
So, let’s first define an author
model. We can do this from the command line:
ember g mirage-model author
This gives us the file
// mirage/models/author.js
import { Model } from 'ember-cli-mirage';
export default Model;
which sets up our database (at run-time) with an authors
table. Now we can rewrite our route handler to use the model.
A schema
object is injected into each route handler as the first parameter, which is how we access our models. Let’s use it to make this route dynamic:
this.get('/authors', (schema) => {
return schema.author.all();
});
Now, Mirage will respond to this route with all the author
models in its database.
You can also create, update and delete models from your route handlers. A request
object is injected as the second parameter, which contains any data that was sent along with the request.
Let’s say your Ember app creates an author by sending a POST request with the following payload:
{
author: {
name: 'Link',
age: 123
}
}
We can use this data to create a new author
model:
this.post('/authors', (schema, request) => {
const attrs = JSON.parse(request.requestBody).author;
return schema.author.create(attrs);
});
This handler creates a new author, inserts it into the database (which assigns it an id
), and responds with that record.
As long as all your Mirage routes read from and write to the database, user interactions will persist during a single session. This lets users interact with your app as if it were wired up to a real server.
The request object that’s injected into your route handlers contains any dynamic route segments and query params.
To define a route that has a dynamic segment, use colon syntax (:segment
) in your path. The dynamic piece will be available via request.params.[segment]
:
this.get('/authors/:id', function(schema, request) {
var id = request.params.id;
return schema.author.find(id);
})
Query params from the request can also be accessed via request.queryParams.[param]
.
Mirage uses Pretender.js to intercept HTTP requests, so check out its docs to see the full API for the request object.
APIs have become more standardized, so Mirage has the concept of shorthands to deal with common scenarios. These shorthands can replace many of your custom route handlers, dramatically simplifying your server definition.
For example, the route handler we wrote above to handle a GET request to /authors
this.get('/authors', (schema, request) => {
return schema.author.all();
});
is pretty standard: it responds with a named collection. The shorthand form of this is
this.get('/authors');
which infers the collection name from the last part of the URL. Returning a single author by id is just as easy:
this.get('/authors/:id');
Similarly, we wrote a mock by hand to deal with creating an author
this.post('/authors', (schema, request) => {
const attrs = JSON.parse(request.requestBody).author;
return schema.author.create(attrs);
});
which is also pretty standard: it creates a new model using the attributes from the request payload. The equivalent shorthand is
this.post('/authors');
View the full reference to see all available shorthands.
When you return a model or a collection from a route handler, Mirage serializes it into a JSON payload, and then responds to your Ember app with that payload. It uses an object called a Serializer to do this, which you can customize. Having a single object that’s responsible for this formatting logic helps keep your route handlers simple. In particular, a bit of customization in the serializer layer often lets you use shorthands when you otherwise wouldn’t be able to.
Mirage ships with two named serializers, JsonApiSerializer (used to mock servers implementing JSON:API) and ActiveModelSerializer (used to mock Rails servers using ActiveModel::Serializers). You should use these if your app’s backend will be built to conform to either standard.
Additionally, there’s a basic Serializer class that you can use and customize. By default, it takes all the attributes of your model, and returns them under a root key of the model type.  Let’s say your backend server returns dasherized object keys instead of camel cased. You can customize the response by extending the base Serializer and overwriting keyForAttribute
:
// mirage/serializers/application.js
import { Serializer } from 'ember-cli-mirage';
import Ember from 'ember';
const { dasherize } = Ember.String;
export default Serializer.extend({
keyForAttribute(key) {
return dasherize(key);
}
});
Now, without having to edit your route handler, the response would look like this:
GET /authors/1
{
author: {
id: 1,
'first-name': 'Keyser',
'last-name': 'Soze',
age: 145
}
}
Just like in Ember, the application/serializer.js
file will apply to all your responses. You can also create per-model serializers, for example to include only some attributes:
// mirage/serializers/author.js
import ApplicationSerializer from './application';
export default ApplicationSerializer.extend({
attributes: ['firstName']
});
View the full Serializer API to learn more about customizing your responses.
You can define associations between your models, which makes dealing with related data easier. For example, let’s say an author has many posts, and when you delete an author your server also deletes all the related posts.
We can define the relationship on our author model:
// mirage/models/author.js
import { Model, hasMany } from 'ember-cli-mirage';
export default Model.extend({
posts: hasMany()
});
hasMany
tells Mirage that it can find this author’s posts using the authorId
field. Now, our route handler for deleting an author looks like this:
this.del('/authors/:id', (schema, request) => {
let author = schema.author.find(request.params.id);
author.posts.delete();
author.delete();
});
A response with DELETE’s default status code of 200 would then be returned.
Associations are also useful in combination with serializers. With the relationship defined above on our author
model, we can use a shorthand and a custom serializer to sideload an author’s related posts:
// mirage/config.js
this.get('/authors/:id');
// mirage/serializers/author.js
import { Serializer } from 'ember-cli-mirage';
export default Serializer.extend({
include: ['posts']
});
Now a request for an author responds with the following:
GET /authors/1
{
author: {
id: 1,
name: 'Link'
},
posts: [
{ id: 1, authorId: 1, title: "The Beauty of Hyrule"},
{ id: 2, authorId: 1, title: "Really, I'm an Elf!"},
{ id: 3, authorId: 1, title: "Ganondorf is my Father"}
]
}
Mirage’s database uses camelcase for all model attributes, including foreign keys (e.g. authorId
in the example above), but you can customize the format that gets sent in the response by overwriting your serializer’s keyForRelatedCollection
. See the serializer guide for more details.
By default, Mirage sets the HTTP code of a response based on the verb being used:
get
, put
and del
are 200post
is 201Additionally, a header for Content-type
is set to application/json
.
You can customize both the response code and headers by returning a Response
in your route handler:
// app/mirage/config.js
import { Response } from 'ember-cli-mirage';
export default function() {
this.post('/authors', function(schema, request) {
let attrs = JSON.parse(request.requestBody).author;
if (attrs.name) {
return schema.author.create(attrs);
} else {
return new Response(400, { some: 'header' }, { errors: ['name cannot be blank']});
}
});
}
Route handlers for paths without a domain (e.g. this.get('/authors')
) work for requests that target the current domain. To mock out other-origin requests, specify the fully qualified URL for your route handler:
this.get('https://api.github.com/users/samselikoff/events', () => {
return [];
});
That’s the essentials of defining your routes. Next, you’ll learn how to seed your database with some starting data, both in development and within tests.

One wouldn't imagine how difficult it can be to copy/move files around. You can come up with cp
/mv
hacks within a few minutes. But doing it right, with user interaction, trash support, percentage/EST calculation and all the good stuff (threaded of course, and esp. without risking data loss on the user's side), seems to be surprisingly difficult. I guess it's time to stand up from the computer and do something else.
In other news, there's Mickael posting about Xfce is KDE done the right way, based on one of Jaspers screenshots: I doubt that Xfce will ever attract the average KDE user. There ain't enough bells and whistles in Xfce, or - to quote a colleague - Xfce just works. KDE users are a bit like Mac Classic users: It doesn't matter that much if something doesn't work properly (they'll figure out how to ignore the problem), but everything must be cute and cuddly. And personally, I wouldn't want to see Xfce turning into that direction.
It's wednesday already. Managed to finish my last math exam successfully this week and now I'm planning for my birthday party next saturday.
There's not much to tell from the Thunar front. I hope to have a release version ready by the end of the month, which will be imported into the Xfce SVN repository then, but no promises. Not sure if we can really release 4.4.0 this year, atleast its questionable for Thunar. But on the other hand, that shouldn't be a problem, as long as we manage to release prior to 20060116. And dropping Thunar from Xfce 4.4.0 now that we told everybody that it will be included with 4.4 won't work.
As always, whats needed the most is time.
While testing some volume manager related stuff, I tried to load a large folder from a CD-ROM (the i386 folder from one of my more or less unused Windows 2000 install CDs, which contains about 4000 files) into the tree view and it took forever, even after the folder content was visible (I suspect this is GtkTreeView loading icon data for the invisible items, tho haven't checked yet). And of course, since currently everything runs in the main thread, the GUI was blocked.
While I was aware of this problem, I decided to ignore it so far. On the solution side, we have basicly two possibilities: First we can do everything asynchronously or secondly we can do the fast stuff synchronously and add a "media://"-implementation, which does its work asynchronously (if somebody has a slow NFS-mount, he won't have fun with most probably every other program either, so we can safely ignore this case and focus on removable media). The first option is actually what I did for the very first prototypes and it turned out to be complex (I don't want to force everything into a limited low-level API like Gnome-VFS does, and so the high-level stuff would need to be thread-safe) and slow. The second option looks better to me, although it's still a lot of work to implement ThunarFolder and ThunarFile in a thread-safe way.
I just removed xfce4-tips from the xfce4-toys package, since it's now included with xfce4-session. Now the question is: Where to move the eyes plugin to (which is the only component left in xfce4-toys)? We have basicly three options:
- Move it to xfce4-panel
- Turn it into a separate goodie
- Drop it (if Danny do not want to maintain it anymore)
Since we're now using desktop files instead of arbitrary scripts or symlinks, it is pretty easy to make the list of autostarted applications editable through a simple user interface. And so here's xfce4-autostart-editor
:
xfce4-autostart-editor
is now part of xfce4-session
(trunk, rev 16232). I'm looking for an icon - or atleast an idea about how such an icon could look like - for this tool (unfortunately Francois is away).

[gecode-users] Extending Actor for actions
David Rijsman
David.Rijsman at quintiq.com
Wed Aug 6 14:34:36 CEST 2008
I am working on a search framework using Gecode and have a question concerning the following.
My search generates a node containing actions to be executed where an action can be an arbitrary operation including generating a disjunction or conjunction of (sub-)actions. The execution of an action consisting out of a disjunction of actions will generate new nodes. Each node (approximately, skipping some optimization) will contain a copy of the Space instance and should contain a copy of the (stack of) actions to be executed. An action can have attributes such as variables and for this reason the clone of the action(stack)s should be included in the clone of the Space instance to make use of the forwarding of the pointers of the variable implementations.
My question is if it is possible to introduce new classes which will be cloned (like the Branching extensions) when the Space::clone is invoked without having to change anything in the Space. I think extending the Actor class might do it but I thought I ask instead of trying to reverse engineer.
hope this makes some sense,

This set of exercises form an important part of the first project. The analytical exercises deal with the material covered last week on the mathematical interpretations of ordinary least squares and of Ridge regression. The numerical exercises can be seen as a continuation of exercise 3 from week 35, with the inclusion of Ridge regression. This material enters also the discussions of the first project.
The aim here is to derive the expression for the optimal parameters using Ridge regression. Furthermore, using the singular value decomposition, we will analyze the difference between the ordinary least squares approach and Ridge regression.
The expression for the standard Mean Squared Error (MSE) which we used to define our cost function and the equations for the ordinary least squares (OLS) method, was given by the optimization problem
$$ {\displaystyle \min_{\boldsymbol{\beta}\in {\mathbb{R}}^{p}}}\frac{1}{n}\left\{\left(\boldsymbol{y}-\boldsymbol{X}\boldsymbol{\beta}\right)^T\left(\boldsymbol{y}-\boldsymbol{X}\boldsymbol{\beta}\right)\right\}. $$which we can also write as
$$ {\displaystyle \min_{\boldsymbol{\beta}\in {\mathbb{R}}^{p}}}\frac{1}{n}\sum_{i=0}^{n-1}\left(y_i-\tilde{y}_i\right)^2=\frac{1}{n}\vert\vert \boldsymbol{y}-\boldsymbol{X}\boldsymbol{\beta}\vert\vert_2^2, $$where we have used the definition of a norm-2 vector, that is
$$ \vert\vert \boldsymbol{x}\vert\vert_2 = \sqrt{\sum_i x_i^2}. $$By minimizing the above equation with respect to the parameters \( \boldsymbol{\beta} \) we could then obtain an analytical expression for the parameters \( \boldsymbol{\beta} \).
We can add a regularization parameter \( \lambda \) by defining a new cost function to be optimized, that is
$$ {\displaystyle \min_{\boldsymbol{\beta}\in {\mathbb{R}}^{p}}}\frac{1}{n}\vert\vert \boldsymbol{y}-\boldsymbol{X}\boldsymbol{\beta}\vert\vert_2^2+\lambda\vert\vert \boldsymbol{\beta}\vert\vert_2^2 $$which leads to the Ridge regression minimization problem. One can require as part of the optimization problem that \( \vert\vert \boldsymbol{\beta}\vert\vert_2^2\le t \), where \( t \) is a finite number larger than zero. We will not implement that here.
Show that the optimal parameters
$$ \hat{\boldsymbol{\beta}}_{\mathrm{Ridge}} = \left(\boldsymbol{X}^T\boldsymbol{X}+\lambda\boldsymbol{I}\right)^{-1}\boldsymbol{X}^T\boldsymbol{y}, $$with \( \boldsymbol{I} \) being a \( p\times p \) identity matrix with the constraint that
$$ \sum_{i=0}^{p-1} \beta_i^2 \leq t, $$with \( t \) a finite positive number. In the optimization, we will not require that the latter is satisfied.
The ordinary least squares result is
$$ \hat{\boldsymbol{\beta}}_{\mathrm{OLS}} = \left(\boldsymbol{X}^T\boldsymbol{X}\right)^{-1}\boldsymbol{X}^T\boldsymbol{y}, $$Here we will use the singular value decomposition of an \( n\times p \) matrix \( \boldsymbol{X} \) (our design matrix)
$$ \boldsymbol{X}=\boldsymbol{U}\boldsymbol{\Sigma}\boldsymbol{V}^T, $$to study properties of Ridge regression and ordinary least squares regression. Here \( \boldsymbol{U} \) and \( \boldsymbol{V} \) are orthogonal matrices of dimensions \( n\times n \) and \( p\times p \), respectively, and \( \boldsymbol{\Sigma} \) is an \( n\times p \) matrix which contains the singular values only. This material was discussed during the lectures of week 35.
Show that you can write the OLS solutions in terms of the eigenvectors (the columns) of the orthogonal matrix \( \boldsymbol{U} \) as
$$ \tilde{\boldsymbol{y}}_{\mathrm{OLS}}=\boldsymbol{X}\boldsymbol{\beta} = \sum_{j=0}^{p-1}\boldsymbol{u}_j\boldsymbol{u}_j^T\boldsymbol{y}. $$For Ridge regression, show that the corresponding equation is
$$ \tilde{\boldsymbol{y}}_{\mathrm{Ridge}}=\boldsymbol{X}\boldsymbol{\beta}_{\mathrm{Ridge}} = \boldsymbol{U\Sigma V^T}\left(\boldsymbol{V}\boldsymbol{\Sigma}^2\boldsymbol{V}^T+\lambda\boldsymbol{I} \right)^{-1}(\boldsymbol{U\Sigma V^T})^T\boldsymbol{y}=\sum_{j=0}^{p-1}\boldsymbol{u}_j\boldsymbol{u}_j^T\frac{\sigma_j^2}{\sigma_j^2+\lambda}\boldsymbol{y}, $$with the vectors \( \boldsymbol{u}_j \) being the columns of \( \boldsymbol{U} \) from the SVD of the matrix \( \boldsymbol{X} \).
Give an interpretation of the results. Section 3.4 of Hastie et al's textbook gives a good discussion of the above results.
This exercise is a continuation of exercise 3 from week 35, see https://compphysics.github.io/MachineLearning/doc/LectureNotes/_build/html/exercisesweek35.html. We will use the same function to generate our data set, still staying with a simple function \( y(x) \) which we want to fit using linear regression, but now extending the analysis to include the Ridge regression method.
In this exercise you need to include the same elements from last week, that is
The addition to the analysis this time is the introduction of the hyperparameter \( \lambda \) when introducing Ridge regression.
Extend the code from exercise 3 from week 35 to include Ridge regression with the hyperparameter \( \lambda \). The optimal parameters \( \hat{\beta} \) for Ridge regression can be obtained by matrix inversion in a similar way as done for ordinary least squares. You need to add to your code the following equations
$$ \hat{\boldsymbol{\beta}}_{\mathrm{Ridge}} = \left(\boldsymbol{X}^T\boldsymbol{X}+\lambda\boldsymbol{I}\right)^{-1}\boldsymbol{X}^T\boldsymbol{y}. $$The ordinary least squares result you encoded last week is given by
$$ \hat{\boldsymbol{\beta}}_{\mathrm{OLS}} = \left(\boldsymbol{X}^T\boldsymbol{X}\right)^{-1}\boldsymbol{X}^T\boldsymbol{y}, $$Use these results to compute the mean squared error for ordinary least squares and Ridge regression first for a polynomial of degree five with \( n=100 \) data points and five selected values of \( \lambda=[0.0001,0.001, 0.01,0.1,1.0] \). Compute thereafter the mean squared error for the same values of \( \lambda \) for polynomials of degree ten and \( 15 \). Discuss your results for the training MSE and test MSE with Ridge regression and ordinary least squares.


RayOnSpark
Run Ray on Spark
AnalyticsZoo has already provided a mechanism to deploy Python dependencies and Ray services automatically
across yarn cluster,meaning python user would be able to run Analytics-Zoo
or Ray
in a pythonic way on yarn without spark-submit
or installing Analytics-Zoo or Ray across all cluster nodes.
Here are the steps to run RayOnSpark:
1) You should install Conda and create a conda-env named "ray36"
2) Install some essential dependencies in the conda env.
pip install analytics-zoo
pip install pyspark==2.4.0 # 2.4.3 is OK as well.
pip install ray==0.6.6
pip install conda-pack
pip install psutil
pip install aiohttp
pip install setproctitle
3) Download JDK8 and set the environment variable: JAVA_HOME (recommended).
- You can also install JDK via conda without setting the JAVA_HOME manually:
conda install -c anaconda openjdk=8.0.152
4) Start python and then execute the following example
- Create a SparkContext on Yarn
import ray
from zoo import init_spark_on_yarn
from zoo.ray.util.raycontext import RayContext
slave_num = 2
sc = init_spark_on_yarn(
hadoop_conf="/opt/work/almaren-yarn-config/",
conda_name="ray36",
num_executor=slave_num,
executor_cores=4,
executor_memory="8g",
driver_memory="2g",
driver_cores=4,
extra_executor_memory_for_ray="10g")
- [Optional] If you don't have a yarn cluster, this can also be test locally by creating
SparkContext
withinit_spark_on_local
from zoo import init_spark_on_local
sc = init_spark_on_local(cores=4)
-
Once the SparkContext created, we can write more logic here either training Analytics-Zoo model or launching ray on spark.
-
The following code would launch a ray cluster on top of the SparkContext configuration and also verify with a simple Ray example.
ray_ctx = RayContext(sc=sc,
object_store_memory="5g")
ray_ctx.init()
@ray.remote
class TestRay():
def hostname(self):
import socket
return socket.gethostname()
def check_cv2(self):
# conda install -c conda-forge opencv==3.4.2
import cv2
return cv2.__version__
def ip(self):
import ray.services as rservices
return rservices.get_node_ip_address()
actors = [TestRay.remote() for i in range(0, slave_num)]
print([ray.get(actor.hostname.remote()) for actor in actors])
print([ray.get(actor.ip.remote()) for actor in actors])
ray_ctx.stop()
- NOTE: This was test on Ray 0.6.6. Ideally, we can upgrade to the latest version once the following issue is addressed.(https://github.com/ray-project/ray/issues/5223)


Pointers and references look different enough (pointers use the
* and
-> operators, references use
.), but they seem to do similar things. Both pointers and references let you refer to other objects indirectly. How, then, do you decide when to use one and not the other?
First, recognize that there is no such thing as a null reference. A reference must always refer to some object. As a result, if you have a variable whose purpose is to refer to another object, but it is possible that there might not be an object to refer to, you should make the variable a pointer, because then you can set it to null. On the other hand, if the variable must always refer to an object, i.e., if your design does not allow for the possibility that the variable is null, you should probably make the variable a reference.
"But wait," you wonder, "what about underhandedness like this?"
1 2 3
|
char *pc = 0; // set pointer to null
char& rc = *pc; // make reference refer to
// dereferenced null pointer
| |
Well, this is evil, pure and simple. The results are undefined (compilers can generate output to do anything they like), and people who write this kind of code should be shunned until they agree to cease and desist. If you have to worry about things like this in your software, you're probably best off avoiding references entirely. Either that or finding a better class of
programmers to work with. We'll henceforth ignore the possibility that a reference can be
null.
Because a reference must refer to an object,
C++ requires that references be initialized:
1 2 3 4
|
string& rs; // error! References must
// be initialized
string s("xyzzy");
string& rs = s; // okay, rs refers to s
| |
Pointers are subject to no such restriction:
1 2
|
string *ps; // uninitialized pointer:
// valid but risky
| |
The fact that there is no such thing as a null reference implies that it can be more efficient to use references than to use pointers. That's because there's no need to test the validity of a reference before using it:
1 2 3 4
|
void printDouble(const double& rd)
{
cout << rd; // no need to test rd; it
} // must refer to a double
| |
Pointers, on the other hand, should generally be tested against null:
1 2 3 4 5 6
|
void printDouble(const double *pd)
{
if (pd) { // check for null pointer
cout << *pd;
}
}
| |
Another important difference between pointers and references is that pointers may be reassigned to refer to different objects. A reference, however, always refers to the object with which it is initialized:
1 2 3 4 5 6 7 8 9 10 11 12
|
string s1("Nancy");
string s2("Clancy");
string& rs = s1; // rs refers to s1
string *ps = &s1; // ps points to s1
rs = s2; // rs still refers to s1,
// but s1's value is now
// "Clancy"
ps = &s2; // ps now points to s2;
// s1 is unchanged
| |
In general, you should use a pointer whenever you need to take into account the possibility that there's nothing to refer to (in which case you can set the pointer to null) or whenever you need to be able to refer to different things at different times (in which case you can change where the pointer points). You should use a reference whenever you know there will always be an object to refer to and you also know that once you're referring to that object, you'll never want to refer to anything else.
There is one other situation in which you should use a reference, and that's when you're implementing certain operators. The most common example is
operator[]. This operator typically needs to return something that can be used as the target of an assignment:
1 2 3 4 5
|
vector<int> v(10); // create an int vector of size 10;
// vector is a template in the
// standard C++ library
v[5] = 10; // the target of this assignment is
// the return value of operator[]
| |
If operator[] returned a pointer, this last statement would have to be written this way:
*v[5] = 10;
But this makes it look like v is a vector of pointers, which it's not. For this reason, you'll almost always want
operator[] to return a reference.
References, then, are the feature of choice when you know you have something to refer to, when you'll never want to refer to anything else, and when implementing operators whose syntactic requirements make the use of pointers undesirable. In all other cases, stick with pointers.


Todd Chrisley Criticizes Nanny Faye’s Pork Rinds & Wine Pairing

Todd Chrisley Criticizes Nanny Faye’s Pork Rinds & Wine Pairing
As Chrisley Knows Best fans would agree, Nanny Faye is a bit of an odd bird that likes to march to the beat of her own drum. Todd Chrisley, however, thinks his mother may have taken things a little too far with her decision to pair pork rinds and wine.
A few hours ago, the Chrisley Knows Best official Instagram account shared a two part video clip featuring the reality TV series family preparing for their weekend getaway.
The clip kicked off with Savannah Chrisley’s fiance Nic Kerdiles packing all of the suit cases into the back of the vehicle. Nic questioned why the family had so many suitcases packed.
“Guys aren’t we just leaving for two days?”
Savannah, however, was quick to remind her fiance that she needed a suitcase exclusively for clothing and another suitcase for her cosmetics.
Nanny Faye chimed in on the conversation noting that Nic better get used to it as the family typically needed a u-haul truck to travel anywhere.
Savannah noted that she was thrilled to go on this trip with her family. She, however, was worried whether her fiance would be able to handle being with her father for that long.
Her brother Chase was quick to point out the reason Savannah and her father got along so well was because they were both pyschopaths. She shrugged and rolled her eyes, but she didn’t shut down what her brother said. In fact, she gave him permission to “call it what you want.”
When the video transitioned back to preparing for the trip, Todd took a dig at Nic as he noted he was happy his dauther’s future husband could come on the trip after bailing on a recent lunch date.
“Of course, family is priority.” Nic responded.
Todd, however, was quick to shoot that down too. He noted God was the most important, followed by himself, and then the rest of the family.
When Nic tried to load Nanny Faye’s cooler into the back of the vehicle, she was quick to snatch it away from him. She admitted she wanted to make sure it made it there.
Loading...
Todd noticed her attachment and wanted to understand why she needed a cooler for a three hour road trip.
Nanny Faye explained the cooler had her wine, pork rinds, and beef jerky inside.
“Who the h*ll drinks wine and eats pork rings?”
His mother quickly educates him that chardonnay pairs better with pork rinds then anything else.
The clip concludes with Savannah cracking up as she places one of her hands reassuringly on her father’s shoulder.


Envisioning a better future for caregivers on campus.
The COVID-19 pandemic has revealed our inability to support those who support others.
The failure of our institutions to support our most vulnerable workers has profoundly harmed so many members of our community. As the pandemic wanes and the rebuilding begins, we must do better for the caregivers among us.
Join the VFC as we document the conditions of caregivers on campus, and take action to fight for a better future.
Caregivers are people who have at-home care responsibilities: for children, for parents, for siblings, for partners, for other loved ones. With the collapse of external caregiving resources, like schools, elder-care facilities, and offices, many of us are being asked to shoulder an impossible burden: full-time care and full-time work.
This project focuses on the students and staff who are serving as caregivers while working on college campuses, from TAs to tenured professors, librarians, adjunct instructors, and administrative staff. We already know that caregiving during the pandemic is harming the emotional, physical, and financial well-being of our community. Because caregiving responsibilities disproportionately fall on women and people of color, we also know that this harm is inequitably distributed. We have an obligation to respond.
Since October of 2020, the Visionary Futures Collective has been inviting campus workers around the world to share their experiences working from home while caring for parents, children, and other loved ones. So far, we have received over 300 responses from caregivers at universities who shared details about the kinds of financial, logistical, and communicative support they are receiving from their institutions.
What we learned is that campus workers overwhelmingly feel abandoned.

Tell Your Story: Take the Survey
The information published on this website was collected through a public google form that was first made available in October of 2020. The questions were modified once, in November. The information shown here represents the merging of the two forms.
The information shown here was last updated on February 18, 2021. It represents 311 respondents from the United States, Canada, Mexico, and Europe. Of these respondents, 15% are caring for more than two people. 33% are caring for adults 18 or over. 5% are students, 10% are contingent or precarious, and 85% have some job security. 70% of respondents are faculty or other instructional staff.
Over 300 campus caregivers answered our question: how do you feel your institution is supporting you? This map shows the percentage of respondents from each state that reported feeling "abandoned" by their institutions. White indicates no response; blue indicates a high level of support; and red indicates little or no support at all.
Over 150 respondents provided information about their level of job security, which allows us to identify caregiver feelings in relation to their position on campus. While this chart makes it clear that students are struggling, it also shows that people in all positions are struggling, too.
The Visionary Futures Collective has put together a collection of advocacy resources that you can use to improve support for caregivers on your campus. The activities, data points, and testimonies below all draw on more than 300 responses to our Caregivers Survey.
Not sure where to start? Our public spreadsheet lists seventeen ways that institutions can take action to support caregivers.
The grid below contains nine strategies you can use to support change on your campus, organized loosely around three approaches to creating change: Shared Vulnerability, Radical Transparency, and Collective Action.
Each strategy is accompanied by a testimony submitted by campus workers. You can view the text of the sound clips here.

Rusty Chicken Thights
By Chef John
"I'm going to show you how to make this incredibly simple and highly effective grilled chicken marinade. It's so perfect and juicy and flavorful. It's an overall gorgeous way to grill chicken."
Ingredients
1 clove garlic, sliced, or more to taste
2 teaspoons Asian chile peeper sauce
1 1/2 tablespoons maple syrup
2 tablespoons soy sauce
2 table spoons mayonnaise
Directions
1
Mash garlic to a paste with a mortar and pestle.  Cover dish with plastic wrap and refrigerate about 3 hours; if preferred, let stand about 30 minutes at room temperature. Unwrap dish and sprinkle with salt.
3
Preheat charcoal grill to high heat.
4
Place chicken thighs onto the hot grill with smooth sides down. Cook until chicken shows grill marks, about 3 minutes. Turn chicken over and cook until other side shows grill marks, about 5 minutes. Continue to cook, moving them occasionally and turning over every 2 minutes, until meat is no longer pink inside and the thighs are golden brown, 10 to 12 minutes.
5
Transfer chicken to a platter, let rest for 5 minutes, and serve garnished with lime wedges.
