FAQ
How does Machbarschaft work for you as a helper?
On the map of our free app "Machbarschaft" you can find out who needs help in your area.
If you click on the request, you will find details about the type of request. Once you have decided
to accept the request, the phone number of the person seeking help will be displayed. Call the
person and clarify the exact need, time frame and payment method. Let us know when you are on the
road and we will automatically inform the person seeking help.
Let's go - We look forward to your feedback!
How does the transfer of goods and payment work?
In general, this is a free service based on your voluntary commitment. Please discuss the shopping
list in advance by phone call with the person seeking your help. Further, you can also arrange the
purchasing method individually (pay before or after the service? pay in cash or another method?
In order to ensure full transparency, we ask you to keep all receipts. Please avoid physical
contact when handing over and receiving the payment for the goods! Keep a minimum distance of 1m to
2m by parking your goods at the apartment door. The cash should optimally be placed in an envelope
or similar in front of the door. Through this measures, both sides are protected from spreading the
infection in the best possible way.
When is the settlement to be executed?
You determine the exact time frame by telephone with the person to be supported.
What do I do if I cannot reach the person by phone?
It is possible that the person cannot be reached by telephone at short notice. Here we ask you to
try again. If it does not work again, you are welcome to reject the request, so that it will be
added to the request pool again.
Target audience/ persona:
"Machbarschaft" was brought to life for a specific reason - the Corona crisis. We want to connect
people with each other, emphasize solidarity and above all provide help where it is urgently needed.
The offer of “Machbarschaft” is directed at people who are subject to greater restrictions than the
general public due to COVID-19. Thus, they rely on extensive support through social contacts who
e.g. can conduct everyday tasks outdoor such as grocery shopping or get medicine at the pharmacy.
Above all, we especially support groups at high risk including elderly as well as people with
previous illnesses.
We want to connect people who belong to a risk group due to age or health reasons with people who
voluntarily support them during this time and thus contribute to their protection.
Our guidelines are based on the following values:
Protection – Our primary goal is to slow the spread of the
COVID-19 virus and to protect risk groups. When handing over the shopping, we aks you to keep at
least 1 - 2 m distance by placing the shopping in front of the apartment door. In case of cash
payment, the appropriate cash is placed in an envelope in front of the apartment door.
Commitment – Agreed transactions are carried out to the best
of our knowledge and belief and within the agreed time frame.
Trust – In order to protect those seeking help in the best
possible way, we carry out an individual identity check. In addition, keep the invoice document of
the purchases made for transparency maintenance.
Discretion – We handle your personal data responsibly and
protect the privacy of helpers and people seeking help.
Voluntary & neighbourly commitment – No remuneration is
claimed for the service provided. We ask for an attentive and careful contact between each other.
Especially in this exceptional situation, our society depends on everyone sticking together as best
as they can.

defparameter
name initial-value [documentation] ⇒ name
defvar
name [initial-value [documentation]] ⇒ name
name—a symbol; not evaluated.
initial-value—a form; for defparameter, it is always evaluated, but for defvar it is evaluated only if name is not already bound.
documentation—a string; not evaluated.
defparameter and defvar establish name as a dynamic variable.
defparameter unconditionally assigns the initial-value to the dynamic variable named name. defvar, by contrast, assigns initial-value (if supplied) to the dynamic variable named name only if name is not already bound.
If no initial-value is supplied, defvar leaves the value cell of the dynamic variable named name undisturbed; if name was previously bound, its old value persists, and if it was previously unbound, it remains unbound.
If documentation is supplied, it is attached to name as a documentation string of kind variable.
defparameter and defvar normally appear as a top level form, but it is meaningful for them to appear as non-top-level forms. However, the compile-time side effects described below only take place when they appear as top level forms.
(defparameter *p* 1) ⇒ *P* *p* ⇒ 1 (constantp '*p*) ⇒ false (setq *p* 2) ⇒ 2 (defparameter *p* 3) ⇒ *P* *p* ⇒ 3 (defvar *v* 1) ⇒ *V* *v* ⇒ 1 (constantp '*v*) ⇒ false (setq *v* 2) ⇒ 2 (defvar *v* 3) ⇒ *V* *v* ⇒ 2 (defun foo () (let ((*p* 'p) (*v* 'v)) (bar))) ⇒ FOO (defun bar () (list *p* *v*)) ⇒ BAR (foo) ⇒ (P V)
The principal operational distinction between defparameter and defvar is that defparameter makes an unconditional assignment to name, while defvar makes a conditional one. In practice, this means that defparameter is useful in situations where loading or reloading the definition would want to pick up a new value of the variable, while defvar is used in situations where the old value would want to be retained if the file were loaded or reloaded. For example, one might create a file which contained:
(defvar *the-interesting-numbers* '()) (defmacro define-interesting-number (name n) `(progn (defvar ,name ,n) (pushnew ,name *the-interesting-numbers*) ',name)) (define-interesting-number *my-height* 168) ;cm (define-interesting-number *my-weight* 13) ;stones
Here the initial value, (), for the variable *the-interesting-numbers* is just a seed that we are never likely to want to reset to something else once something has been grown from it. As such, we have used defvar to avoid having the *interesting-numbers* information reset if the file is loaded a second time. It is true that the two calls to define-interesting-number here would be reprocessed, but if there were additional calls in another file, they would not be and that information would be lost. On the other hand, consider the following code:
(defparameter *default-beep-count* 3) (defun beep (&optional (n *default-beep-count*)) (dotimes (i n) (si:
Here we could easily imagine editing the code to change the initial value of *default-beep-count*, and then reloading the file to pick up the new value. In order to make value updating easy, we have used defparameter.
On the other hand, there is potential value to using defvar in this situation. For example, suppose that someone had predefined an alternate value for *default-beep-count*, or had loaded the file and then manually changed the value. In both cases, if we had used defvar instead of defparameter, those user preferences would not be overridden by (re)loading the file.
The choice of whether to use defparameter or defvar has visible consequences to programs, but is nevertheless often made for subjective reasons.
If a defvar or defparameter form appears as a top level form, the compiler must recognize that the name has been proclaimed special. However, it must neither evaluate the initial-value form nor assign the dynamic variable named name at compile time.
There may be additional (implementation-defined) compile-time or run-time side effects, as long as such effects do not interfere with the correct operation of conforming programs.
defvar is affected by whether name is already bound.
declaim, defconstant, documentation; (setf documentation), Compilation
It is customary to name dynamic variables with an asterisk at the beginning and end of the name. e.g., *foo* is a good name for a dynamic variable, but not for a lexical variable; foo is a good name for a lexical variable, but not for a dynamic variable. This naming convention is observed for all defined names in Common Lisp; however, neither conforming programs nor conforming implementations are obliged to adhere to this convention.
The intent of the permission for additional side effects is to allow implementations to do normal "bookkeeping" that accompanies definitions. For example, the macro expansion of a defvar or defparameter form might include code that arranges to record the name of the source file in which the definition occurs.
defparameter and defvar might be defined as follows:
(defmacro defparameter (name initial-value &optional (documentation nil documentation-p)) `(progn (declaim (special ,name)) (setf (symbol-value ',name) ,initial-value) ,(when documentation-p `(setf (documentation ',name 'variable) ',documentation)) ',name)) (defmacro defvar (name &optional (initial-value nil initial-value-p) (documentation nil documentation-p)) `(progn (declaim (special ,name)) ,(when initial-value-p `(unless (boundp ',name) (setf (symbol-value ',name) ,initial-value))) ,(when documentation-p `(setf (documentation ',name 'variable) ',documentation)) ',name))

1.13 CommandAPI
3.0
An API for the command UI introduced in Minecraft 1.13
|
Since the CommandAPI is used to register commands as a vanilla Minecraft command, you may want to use other plugins that are not written with the CommandAPI. For instance, if you want to include a command from a plugin which doesn't use the CommandAPI in a commandblock, _(such as the /execute
command)_, you can use the CommandAPI's command conversion system.
Developer's Note:
The command conversion system is nowhere near perfect. It tries its best to connect Bukkit plugins to vanilla Minecraft commands, but is not guaranteed to run flawlessly. If possible, consider forking/requesting a plugin and writing it with compatibility for the CommandAPI.
To register all commands that are declared by a plugin, the Converter.convert(Plugin)
method can be used. This attempts to register all commands declared in a plugin's plugin.yml
file, as well as any aliases or permissions stated in the plugin.yml
file.
It is important to note that the plugin must be loaded before your plugin before attempting conversion. _(Use loadbefore: [YourPlugin, CommandAPI]
to ensure it loads before your plugin)_
Say you have some plugin.yml
file for a plugin.
Then, the following code will register the commands /gmc
, /gm1
, /gms
and /i
:
In addition to converting the whole plugin, the CommandAPI allows you to convert single commands at a time using the Converter.convert(Plugin, String)
method, where the String
argument refers to the command name as declared in the plugin's plugin.yml
file.


CONTACT. (1997) Directed by Robert Zemeckis. Performed by Jodie Foster. Music by Alan Silvestri.
If we see Zemeckis' s career, we can say that this is a director quite interested in the themes of past and youth. In Forrest Gump or in the Back to the Future trilogy, those themes are explored in every way possible. With Contact, Zemeckis shows us again how essential is our knowledge of history and our ability to dream.
Contact is a high budget movie and what is quite surprising, is that it is an interesting film! Indeed, its secret aims have nothing to do with business, but with ideas. To serve some interesting reflections on religion, death or life, Zemeckis has hired a spectacular cast: Jodie Foster, Mathew McConaughey, James Woods, Tom Skeritt or Angela Bassett. Thus, the film is entertaining and can be appreciated by any kind of persons - even those who do not like science-fiction movies since that Contact is not really a movie dealing with extra-terrestrials or the discovery of space, but rather a (re)discovery of human kind, its history (references to Hitler notably) and its emotions. This is not only a spectacular film, it is an intimate one, an inner journey. Besides, it can be said that all the films Jodie Foster is used to playing in are kind of inner journeys. In this film, she really shines, as usual, and she succeeds in exploring her own emotions very deeply and those of the audience at the same time. Will she receive another Academy Award? She deserves it again anyway.
In Contact, the special effects are not there because it is up to date to make movies with special effects, but they really serve the aim of the film: searching for human basic feelings. It is even the paradox of the whole film: new technologies do not really transform us into machines, but make our reactions more human actually! When the E.T. signal is heard for the first time in the movie, the characters (and the audience) feel more human paradoxically, all excited like kids.
The word "kid" is obviously a key-word for describing Contact. Just like Forrest, Foster's character is still a child, fragile but passionate. When we see Contact, we feel the same emotions we had when very young. That is all the magic and the interest of this movie. The film is a homage to the power of imagination. Besides, it has a magical and onirical atmosphere as if the whole movie was like a child dream. And as dreams always reveal who we are, Contact talks to all of us very deeply.

Susan Granger's review of "SLUMS OF BEVERLY HILLS" (Fox Searchlight)
First-time writer/director Tamara Jenkins scores with bawdy humor and solid performances in this bizarre coming-of-age comedy. "Happy families are all alike," reads the prologue. "Every unhappy family has its own story." Based on her own memories of growing up on the wrong side of the 90210 zip code, the story revolves the fractured Abramowitz family whom Ms. Jenkins refers to as "nomads of divorce." The movie begins in 1976, as the downwardly mobile father (Alan Arkin) is once again moving his three children in search of a better lifestyle. Firm in the belief that "furniture is temporary, but education is forever," he is determined to stay within the Beverly Hills school district, even if it's in "Casa Bella," a bleak two-story apartment building with a fancy name and cheap rent. Natasha Lyonne is the adolescent heroine. Confused and impressionable, she must cope with distressingly well-developed breasts, an awkward situation only exacerbated by her dysfunctional father and two insensitive brothers. Complicating the situation, her wild, straight-out-of-detox cousin (Marisa Tomei) arrives - to share her bedroom and teach her how to use a vibrator. Then there's the boy-next-door (Kevin Corrigan) who, in this case, is a Charles Manson-obsessed drug-dealer; the rich uncle and aunt (Carl Reiner, Rita Moreno); and a snobbish, neurotic socialite (Jessica Walter). Ms. Jenkins developed her script at the Sundance Institute - hence Robert Redford's name as executive producer - but her quirky humor is quite heavy-handed and she needs to learn how to do some judicious editing. On the Granger Movie Gauge of 1 to 10, "Slums of Beverly Hills" is a raunchy, rowdy 5, a romp that's probably too vulgar for mature movie-goers but should get laughs from younger audiences.

Hello Curd-nerds!
I’m so glad you found this cheese blog! Now, we all know that half the fun of cheese is taking pictures with it, and this got me thinking – how well does the internet represent our true cheese-loving selves?
Without further ado, please enjoy this list of my top 10 favorite stock photos of people eating cheese:
10. This woman, who clearly thinks her cheese is…suspicious, to say the least:
9. Yeah girl yeah! Just dive into it! I’m proud of you.
8. This woman, who is judging us all, but with cheese:
7. Have you ever been trapped at a table with a hipster who WON’T stop talking about how much they know about cheese, and how you can really just taste the fresh grass the cows ate, and that they wouldn’t be caught DEAD getting cheese from a non-specialty store, and that brie cheese is just the poor man’s camembert? This is that person:
Unrelated: Who just puts a full pepper as a centerpiece? Someone chop that pepper! And is it in a bowl of broccoli?? This party is MADNESS.
6. This baby knows what’s up. I trust this baby.
5. Lady, that’s not….that’s not how you do it.
4. You know the common adage, “Stop and smell the cheese?” Anyway, Karen’s about to get kicked out of this grocery store.
3.
2.
1. It was a tough call on the last and best stock photo, but upon careful reflection, I landed on….CHEESE SCIENCE:
Dissect it. Carefully. On a scale (?). In a petri dish. For science.
This concludes my list of favorite cheese stock photos. Thank you for coming to my TED talk.

This chapter discusses the concepts of mindfulness and self awarness which could be slightly different definitions but at the end is almost the same thing.
I am trying body scan everytime I practice meditation. I start scanning my head first, then gently I move down to my face, neck and shoulders, chest and back, legs and feets. Everytime I am doing this I am trying to just notice the feeling in my body, I am not trying to focusing on thinking to much in that part of my body, just noticing the feeling of comfort or dicomfort, tiredness or strengthness. I really enjoy the relaxation that comes from it.
“My Emotions are Not Me” I like this. I think this would be really helpful in stress periods. I will practice this every time I feel frustration, stress or anger…


Image.capture(silent=false
, frame=false

) [ { optional arguments } ] ->
image
Reads an image from an X window. Unless you identify a
window to capture via the optional arguments block,
when capture
is invoked the cursor will turn into
a cross. Click the cursor on the window to be captured.
Within the optional arguments block, specify
self.filename = "root"
to capture the entire
desktop. To programatically specify the window to be captured,
use self.filename = window_id
, where window_id is
the id displayed by xwininfo(1).
true
, suppress the beeps that signal the
start and finish of the capture process. The bell rings once
to signal the start of the capture and twice to signal the
finish.true
, include the window frame.true
, obtain image
by descending window hierarchy.true
, specifies that the GetImage request used to obtain the image
should be done on the root window, rather than directly on
the specified window. In this way, you can obtain pieces of
other windows that overlap the specified window, and more
importantly, you can capture menus or other popups that are
independent windows but appear over the specified
window.true
, include the border in the
image.A new image.
img = Image.capture { self.filename = "root" }
Image.combine(red_ch=nil, green_ch=nil, blue_ch=nil, opacity_ch=nil) ->image
Combines the grayscale value of the pixels in each image to form a new image.
The red channel of the image specified in the first argument is used as the red channel in the new image. The green channel of the image specified in the second argument is used as the green channel in the new image. The blue channel of the image specified in the third argument is used as the blue channel in the new image. The opacity channel of the image specified in the fourth argument is used as the opacity channel in the new image.
Any of the arguments may be nil. Trailing nil arguments may be omitted. You must specify at least one image argument.
A new image
The same results can be obtained using the composite method and the CopyRed/Green/Blue/OpacityCompositeOp CompositeOperator enum values.

Image.constitute(width, height, map, pixels) -> image
Creates an image from an array of pixels. This method is the
reverse of dispatch
.
Integers
or all Floats
. If the
elements are Integers
, the Integers
must be in the range [0..QuantumRange]. If the elements are
Floats
, they must be in the range [0..1].An image constructed from the pixel data.
image = Image.constitute(width, height, "RGB", pixels)
ConstituteImage
Image.from_blob(string) [ { optional arguments } ] -> array
Creates an array of images from a BLOB, that is, a Binary Large OBject. In RMagick, a BLOB is a string.
A blob can be a string containing an image file such as a JPEG or GIF. The string can contain a multi-image file such as an animated GIF or a Photoshop image with multiple layers. A blob can also be one of the strings produced by to_blob. Control the format of the created image(s) by setting additional Image::Info attributes in the optional block argument.
An array of one or more images constructed from the BLOB.

Image.read(file) [ {
optional arguments } ] -> array
Reads all the images from the specified file.
Note: Because an
image file can contain multiple images or multiple image
layers, read
always returns an array containing 0
or more elements, one element for each image or image layer in
the file.
An image file name or open file object. You can specify other arguments by setting Image::Info attributes in the optional block.
An array containing 0 or more Image objects. If the file is a multi-image file such as an animated GIF or a Photoshop PSD file with multiple layers, the array contains an Image object for each image or layer in the file.

The read method does not accept a StringIO object. If you want to create an image from a string buffer, use from_blob.
ReadImage
Image.read_inline(content) [ { optional arguments } ] -> array
Converts a Base64-encoded image or multi-image sequence to an array of Image objects.
A Base64-encoded string. Generally no optional arguments are required. If the image format cannot be deduced from the image data, you can use the format attribute. If you want to extract a subset of an image sequence, see here.

img[key] -> string
Returns the value of the image property identified by
key. An image may have any number of
properties. Each property is identified by a string (or symbol)
key. The property value is a string. ImageMagick predefines
some properties, including Label
,
Comment
, Signature
, and in some cases
EXIF
.
String
or a
Symbol
.
The value of the property.
mom['Label'] = 'My Mother'
GetImageAttribute
ImageMagick calls properties "attributes." I use the word
"properties" to reduce the confusion with image object
attributes such as rows
and

SetImageAttribute
img <=> other_image -> -1, 0, 1
Compares two images and returns -1, 0, or 1 if img is less than, equal to, or greater than
other_image as determined by comparing
the signatures of the images. If one of the arguments is not an
image, this method raises a TypeError exception (in Ruby 1.6)
or returns nil
(in Ruby 1.8)
In addition to <=>, Image
mixes in the
Comparable
module, which defines the <, <=,
== >=, >, and between?
methods.
The difference
method compares images (for
equality only) but also returns information about the amount
two images differ, which may be more useful.

Adds the overlay image to the target image according to src_percent and dst_percent.
This method corresponds to the -blend option of
ImageMagick's composite
command.
The blend
method can be called with or without
a gravity argument. The gravity, x_offset, and

img.blur_channel(radius=0.0, sigma=1.0[, channel...]]) -> image
Blurs the specified channel. We
convolve the image with a Gaussian operator of the given radius
and standard deviation (sigma) . The blur_channel
method differs from gaussian_blur_channel
in that it uses a separable kernel which is faster but
mathematically equivalent to the non-separable
kernel.
For reasonable results, the radius should be larger than sigma. Use a radius of 0 and

img.bounding_box -> rectangle
The image's bounding box. The bounding box is the rectangle that encloses all the pixels not in the border color. Uses the current fuzz value.
In this example, the bounding box is the gray square enclosing the blue circle. (The coordinates and red circles were added after the bounding box was computed.)
img.change_geometry(string) {|cols,rows,image| block} -> ??? (see Returns)
img.change_geometry(geometry) {|cols,rows,image| block} -> ??? (see Returns)
The change_geometry
method supports resizing a
method by specifying constraints. For example, you can specify
that the image should be resized such that the aspect ratio
should be retained but the resulting image should be no larger
than 640 pixels wide and 480 pixels tall.
The argument may be either a geometry string or a Geometry object.
Change_geometry
yields to the block, passing new
width and height values based on the argument with respect to

img.channel(channel) -> image
Extracts a channel from the image. A channel is a particular color component of each pixel in the [image].
A ChannelType value.
An image in which the RGB values of all the pixels have been set to a gray corresponding to the specified channel value. For example, given a pixel in the original image with the value R=255, G=128, B=0 and the RedChannel argument, the equivalent pixel in the result image will have the value R=255, G=255, and B=255. For the BlueChannel argument, the pixel would have the value R=0, G=0, B=0.
The channel image preserves the tone of the selected RGB component.

ChopImage
img.clone -> image
Same as dup except the frozen state of the original is propagated to the new copy.
A new image
img.clut(clut_image [, channel...]) -> self
Replace the channel values in the target image with a lookup of its replacement value in an LUT gradient image.
The LUT image should be either a single row or column image of replacement colors. The lookup is controlled by the -interpolate setting, especially for an LUT which is not the full length needed by the IM installed Quality (Q) level. Good settings for this is the default 'bilinear' or 'bicubic' interpolation setting for a smooth color gradient, or 'integer' for a direct unsmoothed lookup of color values.
This method is especially suited to replacing a grayscale image with specific color gradient from the CLUT image.
Note that color replacements involving transparency (alpha/matte channel) will lookup the replacement alpha/matte value using the alpha/matte value of the original image. As such correct alpha channel lookup for a pure gray-scale original image will require a copy of that grayscale to be transferred into its alpha channel before applying the -clut operator.
self
ImageMagick's -clut option.
img.color_fill_to_border(x, y, fill_color) -> image
Changes any pixel that is a neighbor of the target pixel and is not the border color to the fill color.

img.color_histogram() -> hash
Computes the number of times each unique color appears in the image.
A hash. Each key in the hash is a pixel representing a color that appears
in the image. The value associated with the key is the number
of times that color appears in the image. Caution: if
the image contains many colors the hash will be very large. You
may want to use the quantize
method to reduce the number of colors before using
color_histogram
.
This histogram was produced by sorting the hash returned by
color_histogram
by increasing frequency.
GetImageHistogram
img.colorize(red_pct, green_pct, blue_pct, [matte_pct, ] fill) -> image
Blend the fill color with the image pixels. The red_pct, green_pct, blue_pct and matte_pct arguments are the percentage to blend with the red, green, blue and matte channels.

img.contrast_stretch_channel(black_point [, white_point] [, channel...]) -> image
This method is a simple image enhancement technique that attempts to improve the contrast in an image by `stretching' the range of intensity values it contains to span a desired range of values. It differs from the more sophisticated histogram equalization in that it can only apply a linear scaling function to the image pixel values. As a result the `enhancement' is less harsh.

Extracts the specified rectangle from the image.
The crop method can be called three different ways:
crop
method retains the offset
information in the cropped image. This may cause the image to
appear to be surrounded by blank or black space when viewed
with an external viewer. This only occurs when the image is
saved in a format (such as GIF) that saves offset information.
To reset the offset data, add true

I am a senior at BASIS Scottsdale High School with a love for research, computing, social activism, and dance. I have over 10 years of extensive training in Indian Classical Dance and have used dance as a vehicle for my social activism and gender equality campaigns. When I am not dancing, I like to explore the applications of computer science to medical research. Over the past three years, I have worked on a computational biology project to identify effective chemotherapy regimens at the Harvard Medical School's Boston Children's Hospital, pursued computational neuroscience research at the Barrow Neurological Institute, and conducted independent research on the impact of social media on gender perceptions.
Have conducted scientific research since 9th grade, specializing in computational biology and neuroscience.
Founded 501(c)(3) nonprofit to empower youth through after-school STEM programs.
Co-founder, -director, and -performer of a dance production to raise awareness about gender disparity.
Lead team to sponsor the education of girls in low-income communities around the world.
My inquisitive nature and fascination with science led me to conduct my first research project in middle school. In high school, I have had the honor of interning at formal research institutions such as Barrow Neurological Insitute and Boston Children's Hospital through selective application processes.
I was selected as 1 of 7 students in Arizona to be a research intern at BNI as part of the Scientific Enrichment Program for Students in 10th grade. Under the direction of Dr. Leslie Baxter, I have been working in the Neuroimaging Lab, focused on exploring funtional connectivity for aging autistic patients. I am currently researching computational machine learning methods to provide greater insights on the compounding effects of aging on these individuals.
As a 2016 Research Science Institute (RSI) Scholar, I was selected to intern at Harvard Medical School - Boston Children's Hospital the summer of my junior year as 1 of 82 high school juniors around the world. RSI is a six-week fully paid research program held at MIT. At BCH, I worked under the mentorship of Dr. Gil Alterovitz to develop a computational model to identify effective chemotherapy regimens.

Since the age of five, I have trained in the Classical Indian dance form Bharatnatyam. In 2014, after 10 years of training, I had my Arangetram (graduation performance). I enjoy performing and showcasing my art at cultural programs, the Talking Stick Sports Arena, annual programs, and community gala events. My two biggest dance accomplishments have been AZA and my Arangetram.
I co-founded AZA with 3 other dance partners in the summer of ninth grade. AZA, meaning hope in Sanskrit, is a dance production that portrays the various social issues related to gender disparities that impact our society. Each choreography highlights a different issue such as educational inequities and abusive relationships. We leveraged our passion for dance as a medium to promote social awareness. AZA is an annual performance.
Our first performance was premiered at the Tempe Center for the Arts in January, 2015 to a fully sold-out audience of over 600 people. The show raised $7,000 for She's the First BASIS Scottsdale to sponsor the education of six girls in Uganda, Ethiopia, Peru, India, and Guatemala.
Our second performance was at the AMWA Annual Gala Event in February, 2016. We raised awareness of gender inequities in front of an audience of over 250 people. AMWA's mission is to improve the economic status of women from all ethnic and religious backgrounds residing in our community.
An Arangetram marks the completion of the initial dance training for a student, and it translates to "ascending the stage." My Arangetram was a 3 hour solo debut performance at the Mesa Arts Center in June, 2014. Under the tutelage of Mrs. Nita Mallya, this performance marked the culmination of 10 years of rigorous training. Various live musical instruments and vocalists accompanied my performance.
Technology plays a significant role in many of my academic and creative endeavors. I first became engaged in technology through Photoshop and creative graphics design in middle school. Ever since, I have self-taught various programming languages such as Python, R, MATLAB, and HTML. The tech initiative that I'm most proud of is STEMxCHANGE, a nonprofit to empower other youth through a STEM education.
I founded STEMxCHANGE as a 501(c)(3) nonprofit. Our mission is to empower youth through free STEM education. I have partnered with after-school programs and received a $3,000 grant from NCWIT to promote our program in the community. Currently, I oversee and direct 5 active chapters.
See Website!
As the Science and Tech columnist for my school newspaper, I decided to create an online edition of the newspaper to increase viewership and participation.
See Website!
As a sophomore, I was selected as the Maricopa County STEM Youth Role Model to promote STEM to middle-school students.
See Video!
I have promoted gender equality within my community through dance and STEM outreach. In 10th grade, I also founded the BASIS Scottsdale Chapter of She's the First and was awarded Townsend National Chapter Leader of the Year in 2015.
She’s the First BASIS Scottsdale has fundraised over $8,000 to sponsor the education of eight girls around the world. Our overall goal is to help unlock the potential of our world by providing as many people as possible with educational opportunities. As founder and president, I lead a team of 20 girls and boys.

A named pipe is a mechanism that enables interprocess communication for applications to communicate locally or remotely. The appication that creates the pipe is known as the pipe server, and the application that connects to the pipe is known as the pipe client. Similar to sockets, after the server creates the named pipe, pipe clients may connect to the server"
http://www.blakewatts.com/namedpipepaper.html
Named Pipes Access Rights
Access is defined by a security descriptor
The ACLs in the default security descriptor for a named pipe grant full control the the LocalSystem account, administrators, and the creator owner. They also grant read access to members of the Everyone group and the anonymous account.

I was inspired to build the Password Generator by the linux command pwgen, and by xkcd.com/936/.
Each of the languages uses a wordlist of around 40,000 words, so three words are enough to give a strong password. The downside is that some of the words are so rare only serious Scrabble players are likely to appreciate them.

Host mode networking
Estimated reading time: 2 minutesThese are the docs for UCP version 3.0.16
To select a different version, use the selector below.
By default the layer 7 routing components communicate with one another using overlay networks. You can customize the components to use host mode networking instead.
You can choose to:
- Configure the
ucp-interlock
anducp-interlock-extension
services to communicate using host mode networking. - Configure the
ucp-interlock-proxy
and your swarm service to communicate using host mode networking. - Use host mode networking for all of the components.
In this example we’ll start with a production-grade deployment of the layer 7 routing solution and update it so that use host mode networking instead of overlay networking.
When using host mode networking you won’t be able to use DNS service discovery, since that functionality requires overlay networking. For two services to communicate, each service needs to know the IP address of the node where the other service is running.
Production-grade deployment
If you haven’t already, configure the layer 7 routing solution for production.
Once you’ve done that, the ucp-interlock-proxy
service replicas should be
running on their own dedicated nodes.
Update the ucp-interlock config
Update the ucp-interlock service configuration so that it uses host mode networking.
Update the PublishMode
key to:
PublishMode = "host"
When updating the ucp-interlock
service to use the new Docker configuration,
make sure to update it so that it starts publishes its port on the host:
docker service update \
--config-rm $CURRENT_CONFIG_NAME \
--config-add source=$NEW_CONFIG_NAME,target=/config.toml \
--publish-add mode=host,target=8080 \
ucp-interlock
The ucp-interlock
and ucp-interlock-extension
services are now communicating
using host mode networking.
Deploy your swarm services
Now you can deploy your swarm services. In this example we’ll deploy a demo service that also uses host mode networking. Set up your CLI client with a UCP client bundle, and deploy the service:
docker service create \
--name demo \
--detach=false \
--label com.docker.lb.hosts=app.example.org \
--label com.docker.lb.port=8080 \
--publish mode=host,target=8080 \
--env METADATA="demo" \
ehazlett/docker-demo
Docker allocates a high random port on the host where the service can be reached. To test that everything is working you can run:
curl --header "Host: app.example.org" \
http://<proxy-address>:<routing-http-port>/ping
Where:
<proxy-address>
is the domain name or IP address of a node where the proxy service is running.<routing-http-port>
is the port you’re using to route HTTP traffic.
If everything is working correctly, you should get a JSON result like:
{"instance":"63b855978452", "version":"0.1", "request_id":"d641430be9496937f2669ce6963b67d6"}

SwiftSky let’s you easily integrate the Dark Sky API into your Swift apps.
Requirements
- A Secret Key from darksky.net/dev/register
- iOS 8.0+ / macOS 10.10+ / tvOS 9.0+ / watchOS 2.0+
- Xcode 8.1+
- Swift 3.0+
Installation
CocoaPods
CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:
$ gem install cocoapods
CocoaPods 1.1.0+ is required to build SwiftSky
To integrate SwiftSky into your Xcode project using CocoaPods, specify it in your Podfile
:
use_frameworks!
target '<Your Target Name>' do
pod 'SwiftSky', '~> 1.3'
end
Then, run the following command:
$ pod install
Carthage
Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.
You can install Carthage with Homebrew using the following command:
$ brew update
$ brew install carthage
To integrate SwiftSky into your Xcode project using Carthage, specify it in your Cartfile
:
github "AppCompany/SwiftSky" ~> 1.3
Run carthage update
to build the framework and drag the built SwiftSky.framework
into your Xcode project.
Swift Package Manager
The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift
compiler. It is in early development, but SwiftSky does support its use on supported platforms.
Once you have your Swift package set up, adding SwiftSky as a dependency is as easy as adding it to the dependencies
value of your Package.swift
.
dependencies: [
.Package(url: "https://github.com/AppCompany/SwiftSky.git", majorVersion: 1)
]
Usage
Setup
First you must import SwiftSky everywhere you require to use it
import SwiftSky
Then before requesting any forecasts set the secret you got from darksky.net/dev/register
SwiftSky.secret = "<DARKSKY_SECRET>"
Settings
Optionally you can set the following settings as you wish (default values shown below)
SwiftSky.hourAmount = .fortyEight
SwiftSky.language = .english
SwiftSky.locale = .autoupdatingCurrent
SwiftSky.units.temperature = .fahrenheit
SwiftSky.units.distance = .mile
SwiftSky.units.speed = .milePerHour
SwiftSky.units.pressure = .millibar
SwiftSky.units.precipitation = .inch
SwiftSky.units.accumulation = .inch
For more details on these settings check the documentation
SwiftSky persists all your settings for you throughout a session. Simply set them once at app initialization and your good to go. You can change the settings anytime you want, though they will only be applied to new forecasts being requested.
Requesting a Forecast
There is one simple but versatile function for requesting forecasts SwiftSky.get()
. The function requires you to specify what data you want for which location. The below example displays all possible data types there are. The location accepts a LocationConvertible
meaning you can pass it a Location
, CLLocation
, CLLocationCoordinate2D
or a String
formatted as such: "<latitude>,<longitude>"
SwiftSky.get([.current, .minutes, .hours, .days, .alerts],
at: Location(latitude: 1.1234, longitude: 1.234)
) { result in
switch result {
case .success(let forecast):
// do something with forecast
case .failure(let error):
// do something with error
}
}
Time Travel
Time travel requests are also possible simple give the SwiftSky.get
function a Date
like so:
SwiftSky.get([.hours],
at: Location(latitude: 1.1234, longitude: 1.234),
on: Date(timeIntervalSince1970: 0)
) { result in
// handle like a regular forecast call
}
The Forecast Object
The details of the Forecast
object and all the data it contains can be found here

public class SerialBlob extends Object implements Blob, Serializable, Cloneable
BLOB
value.
The SerialBlob
class provides a constructor for creating
an instance from a Blob
object. Note that the
Blob
object should have brought the SQL BLOB
value's data over
to the client before a SerialBlob
object
is constructed from it. The data of an SQL BLOB
value can
be materialized on the client as an array of bytes (using the method
Blob.getBytes
) or as a stream of uninterpreted bytes
(using the method Blob.getBinaryStream
).
SerialBlob
methods make it possible to make a copy of a
SerialBlob
object as an array of bytes or as a stream.
They also make it possible to locate a given pattern of bytes or a
Blob
object within a SerialBlob
object
and to update or truncate a Blob
object.

A couple caveats before we begin
- Much of what I'm going to be discussing is largely not how I have interacted with research to this point. Instead, it represents an ideal that I am working towards.
- None of what I will talk about should be taken as a referendum on you or your current practices. However, I hope to convince you that you should be working toward the reproducible research ideal, and that, as a field, we should be moving toward reproducible research being the minimal standard.
- I will be focusing on reproducible research with R. Other options are available but, in my view, none are as clear, comprehensive, and easy to implement as the tools at your disposal through R.


--- title: Button layout: component ---
Start your component pages with a quick description of the component, such as:
Quite possibly the single most common graphical user interface element, the push button triggers a single action within an application.
If a component is sufficiently widespread that it takes on a recognizable look across multiple platforms, provide it here. If its appearance varies extremely widely, say so and direct the reader to platform-specific instances.
If a component is sufficiently widespread that some form of typical behavior can be described, describe it here. As with the “Typical Appearance” section, if there is no such consistent behavior, say as much and direct the reader to the platform-specific sections.
Helpful subsections include:
An event is something that can happen to a user interface component. They are both conceptual and highly concrete in that events very frequently translate directly into a user interface component’s API.
The most relevant button event is the click
. A click
event indicates that the user has
triggered the button. Secondary events include hover
, indicating that a pointing device is explicitly
within the button’s bounds.
A state diagram indicating the actions and states of a user interface component.
This is most likely an image. Bonus props if you use SVG.
And also, a state diagram implies, well, states. So be sure to describe them. Note also that there will usually be overlap between a component’s events and its state diagram. A sufficiently detailed state diagram, however, may have more activities than the “public” events that can be reported by a component.
Most button designs have the following states. The enabled
and disabled
states can be
viewed as “dormant” button states—they are the only states that a button can have when a user is not interacting with
it. The enabled
state means that a user can interact with it, while the disabled
state means that a user cannot do so.
When a button is enabled
, additional states may be triggered. Not all states are present in all button
implementations, but in general they are:
hover
: For platforms with an explicit pointing element, positioning that element over a button may
change the button’s appearance. This provides a form of feedback that states that the button will respond if
additional activity is performed.armed
: If the user initiates button-triggered behavior, such as a click on mouse-capable systems,
the button may enter a state indicating that it is ready to be invoked. Many button implementations allow an “out”
from this state, in case the user changes his or her mind in mid-action.Embedded or linked video (by you or by others [and if by others give credit]) showing the component in action.
For components that are available on a web platform, you can embed an actual component right here, such as:
There is almost never just one form of a user interface component. Use this section to address variations on this theme. Some variations are sufficiently different that they are considered to be a different component entirely, despite very similar behavior. Meanwile some variations are due to appearance only.
Talk about the five usability metrics in relation to this component. Not all components will have the same metric priorities. For example:
Because the button is such a fundamental part of virtually every user interface available today, it can be said that all usability metrics are equally important for this component. Users who are seeing a button in a given platform for the first time must not have any issues recognizing it and knowing what to do with it (learnability). The high priority of learnability also implies that memorability is a given.
Users must also never experience undue delays with using a button (efficiency), particularly because using a button almost always involves an instantaneous, immediate-result action. Users should almost never trigger a button by mistake (errors)—especially buttons whose actions result in significant changes to data or the real world.
If any metric at all can be considered as a “low priority” for buttons, it would be satisfaction. The button is such a utilitarian component that “fun” or “enjoyment” is hardly associated with its use. One exception to this prioritization may be for buttons in applications whose primary metric is satisfaction (e.g., games, entertainment). As a part of that overall system, making buttons “fun” may then become more important than in other situations.
This section is for describing “what makes for a good your component here?” Most likely, this is an amalgam of guidelines documents and platform-independent interaction design principles.
Perhaps the most important interaction design principle that a button must follow is feedback. Users must never doubt whether:
This is where things can get really interesting—platform-specific sections go here. Different versions of the same system are considered to be platforms in their own right (e.g., Windows 95 buttons vs. Windows 10 buttons). Completely customized versions of a component (e.g., a unique-looking/-acting button made specifically for a game) are also acceptable here.
The outline for platform-specific entries resembles the outline already described above, except with a focus on how the platform-specific version is different. Thus, you will want some notes on appearance (i.e., more screenshots), behavior, variants, metrics, and characteristics. If some aspect is the same, then say so explicitly so that there is no confusion.
Some platform-specific instances of certain user interface components will merit such a rich discussion that they may require a sizable number of supporting assets. In that case, feel free to add subfolders to the main component folder, named after the platform under examination.
This could well be the most distinctive part of the catalog—the sections above this generally appear in user interface guidelines, albeit with a platform-specific focus. A key premise of the Paradixm project is to compare user interface elements across platforms. Thus, feel free to be creative about presentation here. You might want to display a visual gallery, for example, with links leading to individual pages for each covered platform-specific user interface component.

Simple authorization in MS Orleans cluster
Authorization in Orleans is controlled through the AuthorizeAttribute
attribute and its various parameters. At its simplest, applying the AuthorizeAttribute
attribute to a Grain Interface or Grain Interface Method limits access to the grain or method to any authenticated user.
For example, the following code limits access to the UserGrain
to any authenticated user.
[Authorize]
public interface IUserGrain : IGrainWithStringKey
{
Task<string> DoSomething();
Task<string> DoSomethingElse();
}
If you want to apply authorization to a method rather than the grain, apply the AuthorizeAttribute
attribute to the method itself:
public interface IUserGrain : IGrainWithStringKey
{
[Authorize]
Task<string> DoSomething();
Task<string> DoSomethingElse();
}
Now only authenticated users can access the DoSomething
method and everyone can access DoSomethingElse
method.
You can also use the AllowAnonymous
attribute to allow access by non-authenticated users to individual actions. For example:
[Authorize]
public interface IUserGrain : IGrainWithStringKey
{
[AllowAnonymous]
Task<string> DoSomething();
Task<string> DoSomethingElse();
}
This would allow only authenticated users to the UserGrain
, except for the DoSomething
method, which is accessible by everyone, regardless of their authenticated or unauthenticated / anonymous status.
Warning
[AllowAnonymous]
bypasses all authorization statements. If you combine [AllowAnonymous]
and any [Authorize]
attribute, the [Authorize]
attributes are ignored. For example if you apply [AllowAnonymous]
at the grain level, any [Authorize]
attributes on the same grain (or on any method within it) is ignored.


Here’s a comparison of a standard error message. The first one uses the built-in alert-function, while the second is using sweetAlert.
alert("Oops... Something went wrong!");
sweetAlert("Oops...", "Something went wrong!", "error");
Pretty cool huh? SweetAlert automatically centers itself on the page and looks great no matter if you're using a desktop computer, mobile or tablet. It's even highly customizeable, as you can see below!
In these examples, we're using the shorthand function swal to call sweetAlert.
Event Submitted!
swal("Good job!", "You clicked the button!", "success")
SweetAlert was created by Tristan Edwards, you can follow him on Twitter or Dribbble for updates and other cool projects!
Feel free to fork sweetAlert on GitHub if you have any features that you want to add!
