Data Compression
Decoupling semantic data types from physical data types makes it easier to compress variables. For this example, we restrict ourselves to in-memory compression. Our task is to automatically obtain an efficient in-memory representation, to minimize the RAM used while preserving the same semantic type.
A typical task is data compression, where the user seeks to minimize memory utilization of the machine type representation while preserving the semantic type of their data. We consider a dataset with one variable consisting of “Yes” and “No” values. As the variable has only two distinct values, the machine type storage needed can be optimally stored as a bool using only one byte per value as opposed to a pandas object using approximately 66 bytes. There are infinite potential ways to denote “Yes” and “No” values within a dataset, consequently, we cannot rely on a static rule-based system for inference in general-purpose software. However, that does not mean that this is “just data munging” and we cannot do this and other tasks more effectively. We observe that some patterns occur more often (“Yes”, “No” over “Arr” or “Nay”) and there are other indicators that can help a system to decide what to do (the variable two distinct values). We note that a rule-based system that trivially encodes each variable with two distinct values as boolean is no solution, as the encoding loses part of it’s meaning (e.g. encoding “Male”, “Female”).
Compressio
Compressio performs this lossless in-memory compression of pandas DataFrames and Series powered by the visions type system. This may yield up to 10x less RAM usage for the same data.

ExtentReports is an open-source reporting library for test automation. It is very easily integrated with all test-frameworks (TestNG, JUnit, NUnit etc.) and provides better looking reports. Because Extent is created as a logging utility, it is also possible to use custom logs for each test, add snapshots & videos, assign categories and authors and filter using several parameters. Below are a few quick features of Extent:
The first build for Ruby released on 12/14/2015. We need contributors to help grow this library. Extent uses liquid-markup to render HTML, so knowing it is going to be a big plus.
ExtentMerge is a console application that merges multiple HTML files and DBs from ExtentReports into a single analysis report. It allows viewing all merged test runs from a single report, provides controls to view test history, analysis for each run, top passed and failed

Motion, by its nature, catches the eye. Our brains are well-practiced at interpreting motion, and we can use the smallest details to learn about objects, the relationships between them, and the forces at work when things change.
SKY UX uses motion to shed light on the nature of changes in the system. It uses subtle animation cues to illustrate:
SKY UX does NOT use animations to:
Like other properties of visual design, motion takes advantage of the observer's expectations to simulate physical space in a digital picture. Just as shadows suggest depth and perspective, the details of motion imply properties about objects and the forces between them. SKY UX follows some basic rules to ensure that motion looks natural and realistic and that it demonstrates context to users.
SKY UX uses a set of metaphor-based motion effects. These patterns should be included in the definitions of SKY UX components and should not be invoked directly.
This behavior moves content horizontally or vertically without altering other visual properties such as scale and transparency.
SKY UX primarily employs slide to show/hide content for sidebars and other patterns that use "off-stage" content with an affordance for calling it into view.
Slide should follow these guidelines:
A close relative of slide, this behavior changes the dimensions of containers that toggle between expanded and collapsed views of content. Expand/collapse does not affect the z-order of the container, which means that the surrounding content needs to be moved (using slide) at the same time to make room (or reclaim vacated space).
SKY UX primarily employs expand/collapse to show/hide content that is hidden "on-stage" as part of a progressive disclosure pattern.
Expand/collapse should follow these guidelines:
This behavior shows content that is called or dismissed as a direct consequence of user actions. It uses an eye-catching combination of scale, translation, and transparency transformations. This gives the affected content immediate prominence and also draws a clear relationship between the content and the initiating action that a user performs. Content that emerges is elevated above its surroundings (and calling affordance) in the z-order with a shadow or even a mask over the rest of the page. When the interaction that began with the emerge effect is completed (or abandoned), the content recedes back into its related affordance with a reverse animation.
SKY UX primarily employs emerge/recede to initiate modal dialogues or other interactions that require users to complete tasks before moving on.
Emerge/recede should follow these guidelines:
This behavior navigates into a child record from a parent container. It combines scale and translation to "drill into" the child record, clearly illustrating the change in the scope of the displayed content before and after the transition. The sum of the effects makes the selected child rise above the rest of the page in the z-order, then expand to fill the space of the parent (sometimes the full page). When navigating back to the parent page, the effect reverses.
SKY UX primarily employs drill to navigate to a page that contains content specific to a child member of the previous page.


N.B.: As compatibility of display: flex is IE10+, we use a simple padding to adapt the toggle button with long custom caption

If it can't be drawn, it can't be built. It’s the mantra in our office. Having heard it almost every day that I have been here at Headspring, I never really understood its power before I set out on the (thought to be exciting) task of rebuilding the company website.
I knew I’d have to gather requirements for the site. Having no idea of what requirement gathering techniques were out there I just started a word document list: pages, forms, content. When I sat down with the team to start developing the site, they needed more information about site flow.
I tried explaining with my 17 page word document, highlighted and notes scribbled on the side, but no one was getting it (including myself). When one brilliant person suggested that we draw it out, markers opened and the drawing began: home page, top-nav pages, children pages, forms and so on.
When we were done the picture finally became clear. All my requirements, even those that I had forgotten about, were there and easy to follow. No matter what you’re building, please learn from my mistake and start off drawing your requirements, because if it can’t be drawn, it can’t be built.


Summary of course
Morten Hjorth-Jensen Email<EMAIL_ADDRESS>Department of Physics and Astronomy and Facility for Rare Ion Beams and National Superconducting Cyclotron Laboratory, Michigan State University
Apr 24, 2020
What? Me worry? No final traditional exam in this course!
What did I learn in school this year?
Does this figure that match the experiences you have made this semester?
Topics we have covered this year
- How to derive equations of motion based on forces
- Inertial frames and their relation to accelerating and rotating frames (non-intertial frames)
- Forces, work, energy, angular momentum, linear momentum and conservation laws
- Various types of motions, falling objects, objects moving in various fields
- Analysing energy diagrams and defining effective potential
- Small oscillations, Harmonic oscillator potential and equations of motion
- Transformation of variables that allow for analytical solutions, example two-body problems
- Central forces and two-body problems, center-of-mass and relative coordinates as reference frame
- Two-body scattering problems, classical scattering cross section
- Variational calculus and Lagrangian formalism
- Deriving equations of motion from Lagrangian formalism only
- Lagrangian formalism with constraints
And how to solve these problems
We have studied many systems numerically, from falling objects with and without friction/air resistance, small oscillations (harmonic oscillator), gravitational problems and other central force problems, rotations and the classical pendulum.
- Euler-Cromer and Velocity-Verlet as energy conserving algorithms (time-independent forces)
- Runge-Kutta family of algorithms for time-dependent forces
- Numerical integration using the Trapezoidal, midpoint and Simpson's rule.
One program to rule them all?
DeltaT = 0.001
#set up arrays
tfinal = 10 # in years
n = ceil(tfinal/DeltaT)
# set up arrays for t, a, v, and x
t = np.zeros(n)
v = np.zeros((n,3))
r = np.zeros((n,3))
# Initial conditions as compact 3-dimensional arrays
r0 = np.array([1.0,0.0,0.0])
v0 = np.array([0.0,2*pi,0.0])
r[0] = r0
v[0] = v0
# Start integrating using Euler's method
for i in range(n-1):
# Set up the acceleration for force that depends only on position
a = Force(r)/mass
# update velocity, time and position using the Euler-Cromer forward
v[i+1] = v[i] + DeltaT*a
r[i+1] = r[i] + DeltaT*v[i]
t[i+1] = t[i] + DeltaT
The overarching idea is that as soon as we have analyzed the forces at play, we can reuse our programs (algorithms) with new forces, without having to recur to the few analytical cases we can solve.
Best wishes to you all and thanks so much for your heroic efforts this semester

The promotional film allowed students to work with Ofsted and gain real-life industry experience and insight on video production. The short film explains to viewers how employers can rate and give their views on providers that train their employees, including apprentices and those that are working for them through work experience or work placements.
The video also shows how the online tool enables employers to see feedback from other employers on different providers. This will help them to make informed choices about which education and training provider will best suit their needs.
Praising the work of students from Exeter College, National Director for Further Education and Skills, Lorna Fitzjohn said:
The film is an excellent piece of work. I am very impressed with the professional quality of the video. It is well executed and captures how easy it is to use Employer View to give and view feedback about further education and skill providers across England.
I hope people will take the time to view the video and urge employers to give their feedback on Employer View. The online tool will inform inspectors’ understanding of the effectiveness of provision, increase employers’ engagement in education and training, and help them and employees to choose the provider that is right for them.
Commenting on working with Ofsted to produce the video, Joe Westcott, 2nd year student studying Level 3 BTEC in Creative Media Production said:
Working with Ofsted for a real-world production gives me a great insight of the pipeline of video production.
Together with Ofsted we were able to deliver a promotional video in a small team, helping me to develop the skills necessary for real world production in the industry.
I found working with Ofsted fun and inspiring, something with a rewarding end goal to include in my experience with real-world industry work.
Haydon Beagley, 1st year student studying a Foundation Degree in Animation in Television Production added:
Having the opportunity to create a film for a client like Ofsted has been a truly exciting opportunity. Making a film for an actual client puts the skills that I have learnt in the classroom to work in a real filming situation.
I would highly recommend this to any student who has an interest in filming or wants to know what is expected and what’s demanded from a film like this and working from start to finish from initial ideas to a final product.
The video clip can be viewed on YouTube

Notes to editors
Employer View uses the same model as Learner View, launched in September 2012, which allows learners to register their views on the provision of their further education and skills provider. Employer View will compliment this existing tool, enabling employers to register their views independently of the provider they use. It will enable anyone who accesses the site to see what employers think of any provider in England inspected by Ofsted. Each response registered on Employer View will be completely confidential. Ofsted will not reveal any details of those who register their views to providers. Safeguards are also in place to guard against abuse of the site.

3.9. Feature selection¶
The classes in the sklearn.feature_selection module can be used for feature selection/dimensionality reduction on sample sets, either to improve estimators’ accuracy scores or to boost their performance on very high-dimensional datasets.
3.9.1. Univariate feature selection¶
Univariate feature selection works by selecting the best features based on univariate statistical tests. It can seen as a preprocessing step to an estimator. The scikit.learn exposes feature selection routines a objects that implement the transform method. The k-best features can be selected based on:
- sklearn.feature_selection.univariate_selection.SelectKBest(score_func, k=10)¶
Filter : Select the k lowest p-values
or by setting a percentile of features to keep using
- sklearn.feature_selection.univariate_selection.SelectPercentile(score_func, percentile=10)¶
Filter : Select the best percentile of the p_values
or using common univariate statistical test for each feature:
- sklearn.feature_selection.univariate_selection.SelectFpr(score_func, alpha=0.050000000000000003)¶
Filter : Select the pvalues below alpha based on a FPR test: False Positive Rate: controlling the total amount of false detections.
- sklearn.feature_selection.univariate_selection.SelectFdr(score_func, alpha=0.050000000000000003)¶
Filter : Select the p-values corresponding to an estimated false discovery rate of alpha. This uses the Benjamini-Hochberg procedure
- sklearn.feature_selection.univariate_selection.SelectFwe(score_func, alpha=0.050000000000000003)¶
Filter : Select the p-values corresponding to Family-wise error rate: a corrected p-value of alpha
These objects take as input a scoring function that returns univariate p-values.
Examples:
<IP_ADDRESS>. Feature scoring functions¶
Warning
Beware not to use a regression scoring function with a classification problem.
<IP_ADDRESS>.1. For classification¶
- sklearn.feature_selection.univariate_selection.chi2(X, y)¶
Compute χ² (chi-squared) statistic for each class/feature combination.
This transformer can be used to select the n_features features with the highest values for the χ² (chi-square) statistic from either boolean or multinomially distributed data (e.g., term counts in document classification) relative to the classes.
Recall that the χ² statistic measures dependence between stochastic variables, so a transformer based on this function “weeds out” the features that are the most likely to be independent of class and therefore irrelevant for classification.
Parameters : X : {array-like, sparse matrix}, shape = [n_samples, n_features_in]
Sample vectors.
y : array-like, shape = n_samples
Target vector (class labels).
- sklearn.feature_selection.univariate_selection.f_classif(X, y)¶
Compute the Anova F-value for the provided sample
Parameters : X : array of shape (n_samples, n_features)
the set of regressors sthat will tested sequentially
y : array of shape(n_samples)
the data matrix
Returns : F : array of shape (m),
the set of F values
pval : array of shape(m),
the set of p-values
Feature selection with sparse data
If you use sparse data (i.e. data represented as sparse matrices), only chi2 will deal with the data without making it dense.
<IP_ADDRESS>.2. For regression¶
- sklearn.feature_selection.univariate_selection.f_regression(X, y, center=True)¶
Quick linear model for testing the effect of a single regressor, sequentially for many regressors This is done in 3 steps: 1. the regressor of interest and the data are orthogonalized wrt constant regressors 2. the cross correlation between data and regressors is computed 3. it is converted to an F score then to a p-value
Parameters : X : array of shape (n_samples, n_features)
the set of regressors sthat will tested sequentially
y : array of shape(n_samples)
the data matrix
center : True, bool,
If true, X and y are centered
Returns : F : array of shape (m),
the set of F values
pval : array of shape(m)
the set of p-values
3.9.2. Recursive feature elimination¶
Given an external estimator that assigns weights to features (e.g., the coefficients of a linear model), the goal of recursive feature elimination (RFE) is to select features by recursively considering smaller and smaller sets of features. First, the estimator is trained on the initial set of features and weights are assigned to each one of them. Then, features whose absolute weights are the smallest are pruned from the current set features. That procedure is recursively repeated on the pruned set until the desired number of features to select is eventually reached.
Examples:
- Recursive feature elimination: A recursive feature elimination example showing the relevance of pixels in a digit classification task.
- Recursive feature elimination with cross-validation: A recursive feature elimination example with automatic tuning of the number of features selected with cross-validation.
3.9.3. L1-based feature selection¶
Linear models penalized with the L1 norm have sparse solutions. When the goal is to reduce the dimensionality of the data to use with another classifier, the transform method of LogisticRegression and LinearSVC can be used:
>>> from sklearn import datasets
>>> from sklearn.svm import LinearSVC
>>> iris = datasets.load_iris()
>>> X, y = iris.data, iris.target
>>> X.shape
(150, 4)
>>> X_new = LinearSVC(C=1, penalty="l1", dual=False).fit_transform(X, y)
>>> X_new.shape
(150, 2)
The parameter C controls the sparsity: the smaller the fewer features.
Examples:
- Classification of text documents using sparse features: Comparison of different algorithms for document classification including L1-based feature selection.

- Description
- A common interface for substituting string variables with
other strings.
The substitution algorithm and the syntax for a string variable are
not part of this interface definition. Please look at the documentation
of the implementation that must specify these parameters.

| Methods' Details |
substituteVariables
- Description
- Exchanges variables inside a given text with a substitution text
defined for the variables.
The method iterates through it's internal variables list to match the
variables in the given string. A match replaces the variable with the
string defined for this variable. If no variable can be found in the string
it will be returned unchanged. The behavior if a variable is found in
the string but it is unknown for the implementation depends on the parameter
bSubstRequired.
- Parameter aText

Gray Ridge Brewing started back in 1934 before craft beer was “cool”. We are still a family owned and run brewery! Our little family farm was always an egg and chicken farm until 1930 when it burned down. The Gray family built the farm back up and decided to turn it into a brewery!
We started selling our bottled beer out of our farm house. Word quickly spread and we became a quick hit in Ridgetoen. in 2000, we expanded our brewery and opened up distribution throughout Sourthern Ontario. We remain successful to this day and attribute it all to our secret original family recipe (and beer lovers like you, of course)!
Our brew masters have been raised on the brewery-farm their whole lives and live and breathe to bring you the best beers season after season, year after year. Check in often to see what our brew masters have in store next!
We are proud to be leaders in the industry when it comes to sustainability and eco friendly practices. We bring all returned bottles back to our facilities in Ridgetown, Ontario where they go through a rigorous cleaning and sanitization treatment.
You can find us on tap and in cans at many bars and pubs across Ontario. You can find a selection of our canned and bottled beers at your local Beer Store, Beer Store Retail Partner, or LCBO! You can also purchase cans, bottles, and growlers at our Ridgetown brewery.
Drop in weekdays between 12 and 6pm, and weekends between 11 and 9pm for a guided brewery tour and tasting every hour on the hour*! Or relax with a cold beer poured in our farmhouse taproom. Dogs welcome!
* If bringing a group of 10 or more to any given brewery tour, please book in advance through our
contact form here. We are always happy to accomodate large groups!

io_setup - create an asynchronous I/O context
#include <linux/aio_abi.h> /* Defines needed types */
int io_setup(unsigned nr_events, aio_context_t *ctx_idp);
Note: There is no glibc wrapper for this system call; see
NOTES.
The io_setup() system call creates an asynchronous I/O context suitable
for concurrently processing nr_events operations. The ctx_idp
argument must not point to an AIO context that already exists, and must be
initialized to 0 prior to the call. On successful creation of the AIO context,
*ctx_idp is filled in with the resulting handle.
On success, io_setup() returns 0. For the failure return, see NOTES.
- EAGAIN
- The specified nr_events exceeds the user's limit of available
events, as defined in /proc/sys/fs/aio-max-nr.
- EFAULT
- An invalid pointer is passed for ctx_idp.
- EINVAL
- ctx_idp is not initialized, or the specified nr_events
exceeds internal limits. nr_events should be greater than 0.
- ENOMEM
- Insufficient kernel resources are available.
- ENOSYS
- io_setup() is not implemented on this architecture.
The asynchronous I/O system calls first appeared in Linux 2.5.
io_setup() is Linux-specific and should not be used in programs that are
intended to be portable.
Glibc does not provide a wrapper function for this system call. You could invoke
it using syscall(2). But instead, you probably want to use the
io_setup() wrapper function provided by libaio.
Note that the libaio wrapper function uses a different type
(io_context_t *) for the ctx_idp argument. Note also
that the libaio wrapper does not follow the usual C library
conventions for indicating errors: on error it returns a negated error
number (the negative of one of the values listed in ERRORS). If the system
call is invoked via syscall(2), then the return value follows the
usual conventions for indicating an error: -1, with errno set to a
(positive) value that indicates the error.
io_cancel(2), io_destroy(2), io_getevents(2),
io_submit(2), aio(7)

This is most likely due to the autoDiscover feature of Dropzone.
When Dropzone starts, it scans the whole document, and looks for elements with the
dropzone
class. It then creates an instance of Dropzone for every element found. If you, later on, create a Dropzone instance yourself, you'll create a second Dropzone which causes this error.
So you can either:
Dropzone.autoDiscover = false;
, or
Dropzone.options.myAwesomeDropzone = false;
You don't have to create an instance of Dropzone programmatically in most situations! It's recommended to leave autoDiscover enabled, and configure your Dropzone in the
init
option of your configuration.
There is a
maxFileSize
option in Dropzone which defaults to
256
(MB). Increase this to upload files bigger than that. If your files upload fine but aren't stored on the server, then it's due to your server configuration. Most servers limit the file upload size as well. Please check with the appropriate documentation.
At the moment there isn't a single event to do that, but you can listen to the
complete
event, which fires every time a file completed uploading, and see if there are still files in the queue or being processed.
There is a
maxThumbnailFilesize
option in Dropzone which defaults to
10
(MB) to prevent the browser from downsizing images that are too big. Increase this to create thumbnails of bigger files.
At the moment there isn't a single event to do that, but you can listen to the
complete
event, which fires every time a file completed uploading, and see if there are still files in the queue or being processed.
Dropzone.options.myDrop = { init: function() { this.on("complete", function() { if (this.filesQueue.length == 0 && this.filesProcessing.length == 0) { // File finished uploading, and there aren't any left in the queue. } }); } };
Very often you have to do some verification on the server to check if the file is actually valid. If you want Dropzone to display any error encountered on the server, all you have to do, is send back a proper HTTP status code in the range of 400 - 500.
Dropzone will then know that the file upload was invalid, and will display the returned text as error message.
In most frameworks those error codes are generated automatically when you send back an error to the client. In PHP (for example) you can set it with the
header
command.
Starting with Dropzone version 3.5.0, there is an option that will handle all this for you:
addRemoveLinks
. This will add an
Remove file
element to the file preview that will remove the file, and it will change to Cancel upload if the file is currently being uploaded (this will trigger a confirmation dialog).
You can change those sentences with the
dictRemoveFile
,
dictCancelUpload
and
dictCancelUploadConfirmation
options.
If you still want to create the button yourself, you can do so like this:
<form action="/target-url" id="my-dropzone" class="dropzone"></form>
If your Dropzone element is a
<form>
element, all hidden input fields will automatically be submitted as POST data along with the file upload.
Example:
<form action="/" class="dropzone"> <input type="hidden" name="additionaldata" value="1" />
  <input type="file" name="youfilename" /> etc...
 </form>
To use the information sent back from the server, use the
success
event, like this:
Dropzone.options.myDropzone = { init: function() { this.on("success", function(file, responseText) { // Handle the responseText here. For example, add the text to the preview element: file.previewTemplate.appendChild(document.createTextNode(responseText)); }); } };
Although there's no builtin functionality to do that, you can use Dropzone's default event handlers to your advantage.
The concept is, to create a mock file, and call the event handlers
addedfile
and
thumbnail
to draw the preview.
// Create the mock file: var mockFile = { name: "Filename", size: 12345 }; // Call the default addedfile event handler myDropzone.emit("addedfile", mockFile); // And optionally show the thumbnail of the file: myDropzone.emit("thumbnail", mockFile, "/image/url"); // If you use the maxFiles option, make sure you adjust it to the // correct amount: var existingFileCount = 1; // The number of files already uploaded myDropzone.options.maxFiles = myDropzone.options.maxFiles - existingFileCount;
confirm
implementation
If you are unhappy with the way Dropzone asks a user if she wants to cancel or remove a file, and want to use some other way (e.g.: bootstrap's modal), you can simply overwrite the
Dropzone.confirm
function.
// accepted and rejected are functions to be called whenever the user response // has been received. // rejected is not mandatory! So make sure to check if it exists before // calling it. Do nothing if it doesn't. Dropzone.confirm = function(question, accepted, rejected) { // Do your thing, ask the user for confirmation or rejection, and call // accepted() if the user accepts, or rejected() otherwise. Make // sure that rejected is actually defined! };
You're in luck! Starting with
3.7.0
Dropzone supports the
maxFiles
option. Simply set it to the desired quantity and you're good to go. If you don't want the rejected files to be viewed, simply register for the
maxfilesexceeded
event, and remove the file immediately:
myDropzone.on("maxfilesexceeded", function(file) { this.removeFile(file); });

THE IDOLMAKER A film review by Beth Ravan Copyright 1987 Beth Ravan
THE IDOLMAKER (1980) Directed by Taylor Hackford Starring Ray Sharkey, Tovah Feldshuh, Peter Gallagher
THE IDOLMAKER is a film about a songwriter who takes nobodies and turns them into singing idols during the late 1950s/early 1960s. (Supposedly, it's a fictionalized biography of Bob Marcucci, who presented us with Frankie Avalon and Fabian.) Ray Sharkey plays Vinnie, the songwriter, a driven man who has been struggling for years to get his songs heard. But he knows he doesn't have "the look" that sells, so he finds someone who does and grooms him to become the next teen idol.
His first attempt is a wild success, but he soon loses control of his prodigy and goes off to find another. Vinnie spends half his time wheeling and dealing to create an image and promote his new star, and the other half trying to teach the kid how to sing, how to move, how to support that image when he finally goes public.
Will Vinnie be able to do it again? Will his new star rebel too? And what about all the personal relationships that Vinnie's using and breaking in his drive to make it big? Check it out and see.
OK, this isn't a *great* film, but it is well-made and entertaining. The settings all worked, from the fish market where Vinnie gets some lessons in business from his high-rolling father, to the restaurant where he hangs out. And there's a charming sequence in a tiny apartment where he negotiates with an old woman for permission to take her 16-year-old grandson under his wing (to make him idol #2).
And the characterizations are all good. Sharkey's will be familiar to fans of CBS's WISEGUY; I don't know if this tough-but-vulnerable, charming-yet-driven character is all he can do, but he certainly does it to perfection. Oh, yes - and he sings pretty well, too!
My major beef is a minor quibble with the scenes of the "singing idols" doing their acts. While some of the performances felt like 1959, most definitely did not, and I found it a bit annoying. Still, overall, I'd recommend the film.

So tonight I try X, it's pitch black here as I try to write. 30 minutes since I popped the pill, I'm feeling nothing but they tell me it will come. People are raving around me, in the expected drug-induced stupor I hope to experience. I'm envious. There are familiar faces here, Sarah just talked to me. I lost my train of thought, but they were kind, friendly words so it does not matter.
Dominick is giving Anna a light show, or so it seems. Wait -- no, wrong lifetime. Derrick and Sarah. Eerie how they look more like flickers from a past time. Everyone else is tripping. Should I have done the entire thing? Contemplating taking the other half, probably won't. The chill is gone from the basement, probably more from body heat than anything else. Someone gives me a white sweatshirt. I feel disembodied, as if I'm on too much Concerta but nothing extraordinary. Not the blissful ecstasy I was promised.
Warmth... my eyes widen. They ask if I can feel it.  I definitely feel something, and I'm gnawing impulsively. It passes.
Took the second half, not a minute ago. Might be feeling the first. Maybe. Yeah, like I'm wired on too much Adderall and two days sleep deprived. Silence.  My mouth is dry, cottonmouth perhaps. I'm trying to be bored, but I can't be. My lips are numb and I'm thoughtless; content. Strange, I don't think I'm tripping yet but I'm not sure.
Feel.... good. My arm is asleep, but pleasantly so whenever I move. It seems to require motion. Figures, nothing ever just sits and comes to you. Amusing, but hardly the effects I'm hoping for. I'm beginning to wonder if my body kicked this like it does everything else. A passing moment, nothing more. I will never understand. Everyone else is, why not me? It's been 60 minutes. A $10 disappointment. It could be worse, I suppose, but I was hoping for a new reality to open, or something to that effect.
Squat. I quit, for now. Everyone else, except me.
Woah. Involuntary eye flutter. Feel almost like I'm going to puke, but not. Passes, I think. Derrick suddenly become much better at raving. Strange. Confusion, confusion strobing and pounding sound. Chewing my jaw again, I stand up and run my hands along my hair. Electrical.
I'm disembodied, yet not. Waves of warmth lap over a chill sweat that's formed over my skin, just under my shirt and newly acquired sweatshirt. I smile, yes, this is more what I expected. The lights -- so beautiful, flowing together and bright. The DJ stand is occupied. Transfixed by the lights, oh; the lights. Spinning and twirling, then blurring before my eyes. I wear glasses that scatter the light, and fall into a blissful unawareness of anything except the lights before my eyes. Someone talks, leaving... something about leaving. Hard to focus with all the beautiful colors.
We step outside, it's chill and warm at the same time, and the air smells... fresh. The branches brushed aside are textured, I run my hands along them as we walk to the cars. So strange, yet, appealing. I can't think of any other time I've ever been this content in the moment. I don't want it to stop, never stop. We drive. I wear the glasses, and suddenly a prismatic rainbow city springs to live, filling the night sky with expansive signs and structures. I see a church in the stalagmites, stalagtites and comets shooting about in rainbow facade. Buildings, obelisks... and I'm part of them, but I can't touch. Not yet. They move to the music -- trance, and grow larger only to disappear. So intense, so clear. I almost want to cry. They blur. Arches, many arches gauzy in the night air. I turn my head and they spin into a complex knot to be unwravelled. Where am I? It doesn't really matter. I reach for it, but fail.
We arrive back. Lights splay across the ceiling soon, and I'm once again chasing ripples of light along the ceiling. A turmulteous ocean below of red-orange churns mysteriously, and oil drapes the fan from an everchanging patch along the ceiling. I'm aware of people, but they are second to this. Amazing -- I do not want it to end. But it will, I can feel it coming down. Shivers wrack me as each wave passes I feel more back into reality. Soon the rainbows no longer build streets and landscapes, but rather aimlessly float in chaotic designs. And they are less brilliant. There is conversation, and a bat. Why is there a hat on my head? I remember the feel of felt.
It's over. I'm chewing gum and nursing cartoon dreams and a dry throat. Light -- what a trip. The prismatic drive, the citadels and patterns all so crystal clear and I, bodiless floating amongst it. Surrounded by friends, I never wanted the reality to end of sound and light. Not wanting to give up that last high, then with one final chill rush it disappears. Leaving me wandering, wondering at the world I thought I knew so well.
Fuck. The chill press of the window against my forehead, that utter blanket of warmth and good falling over my shoulders as I reminisce. An experience, for sure. The craving is gone though. Even the memory of it has started to fade. I remember being enraptured by the lights. Always just out of reach but oh-so-brilliant. Sarah said I was child-like. Everything else was insignificant to the lights. And my hair, electrical. My hair felt alive. Tingly, and warm.
Next morning, it's overcast and 10:40am. Some scattered sleep was possible with extremely odd lucid dreaming. Took some vitamins and rehydrated, it all seems so long ago. I'd be gone if ecstasy was addictive. There's no longing anymore, just reality and a wistful memory. Thank you, friends, for making it such for me.

Remarking a person : remark
- Since V1.1
Remarks an existing person in the address book.
Format: remark INDEX r/REMARK
Examples:
-
remark 1 r/Likes to swim.
Edits the remark of the 1st person to beLikes to swim
. -
remark 1 r/
Remove the remark of the 1st person.
Justification
Remarking on individual contact allows the user to keep track of things that he/she supposed to do with that particular contact. This is only one out of many ways to use the remark feature (depending on how the user wants to use the remark feature). For example, assuming there is a remark "meeting John at Starbuck 4pm" added to John’s contact, it will act as a reminder to the user that he/she supposed to meet John at starbuck 4pm. {Justify the need for, and the current design (i.e. external behavior) of, the feature}
Remark mechanism
The remark mechanism is facilitated by Person
, which resides inside Addressbook
. It supports adding a custom remark to individual contact
by utilizing the CLI commands in the Tunedln application.
Person
only deals with Name
, Phone
, Email
, Address
, Birthday
, Remark
, and Tags
.
The following diagram shows the inheritance diagram for Person
:
As you can see from the diagram, Person stores the remark as an attribute. This Person object is then stored in the UniquePersonList, which resides in the AddressBook.
The implementation of the constructor Remark class is shown below in greater detail. Each person in the UnqiuePersonList will have either an empty or textual remark. As you can see from the implementation, Remark require one String input. This input will be provided by the user (which is also owner of the Addressbook), and it will override the existing Remark value (*Note: Empty String is also allowed). Note that this technique of abstraction allows us to further expand Remark into different smaller class to display out a more detailed Remark (E.g. let’s take Address class for instance, it could consists of Block, Street, UnitNo, Postal).
public Remark(String remark) {
requireNonNull(remark);
this.value = remark;
}
The implementation of storing Remark into a Person object is shown below:
public Person(Name name, Phone phone, Email email, Address address, Birthday birthday, Remark remark,
Set<Tag> tags) {
requireAllNonNull(name, phone, email, address, birthday, tags);
this.name = new SimpleObjectProperty<>(name);
this.phone = new SimpleObjectProperty<>(phone);
this.email = new SimpleObjectProperty<>(email);
this.address = new SimpleObjectProperty<>(address);
this.birthday = new SimpleObjectProperty<>(birthday);
this.remark = new SimpleObjectProperty<>(remark);
// protect internal tags from changes in the arg list
this.tags = new SimpleObjectProperty<>(new UniqueTagList(tags));
}
Suppose that the user has just launched the application. Assuming a valid addressbook xml file exists (with numerous person data in it), the UniquePersonList will start storing a list of Person object with correspondence to the xml file. Each person will either have a textual or empty remark.
The user executes an edit
Command by calling edit 1 r/1st try
, to set the 1st person’s
remark to "1st try" in the address book. The existing Remark value will be replaced by the user input "1st try" and
the 1st Person’s object will be updated, since the Remark object is referencing to the 1st Person’s remark attribute.
The user executes another edit command by calling edit 1 r/2nd try
, to replace the remark initial value which is
"1st try" to "2nd try".
| If the edit command fails its execution due to unacceptable syntax, the person’s remark will not be replaced. |
The following sequence diagram shows how the edit remark operation works:
The following activity diagram summarize what happens inside the Person
when a user executes a new command:
Design Considerations
Aspect: Implementation of Remark
Alternative 1 (current choice): Replace the existing Person object with an edited
Person object.
Pros: Neat and Clearer abstractions to be displayed in class diagram.
Cons: Tedious, as the implementation could have be simpler by assigning String as Remark attribute.
Alternative 2: Let String be the attribute for Remark
Pros: Easy to implement.
Cons: Harder to understand the flow of the implementation.
Aspect: Viewing of Remark
Alternative 1 (current choice): Only one remark is able to store for one contact.
Pros: Easy to implement.
Cons: User is unable to keep more than 1 remark.
Alternative 2: Data structure to support multiple remark.
Pros: User is given the choice to overwrite or save a new remark.
Cons: Harder to implement.

command.
Justification
Users such as students or working adults tends to be busy due to the workload. Therefore, they might not be able to keep track of all the events that they supposed to attend to. Hence, by including events mechanism in our app, it allows the user to have a simple and beautiful event calendar which take notes of events on certain dates.
Event mechanism
The event mechanism is facilitated by EventBook
, which resides inside ModelManager
. It supports the additional
features of event management, which allows the user to add, edit, delete, find, or select event.
Export : export
- Since V1.5
Exports the TunedIn application data (either event book or address book) into csv format.
Format: export BOOK
Examples:
-
export addressbook
Exports the addressbook into csv format
Justification
In the case where data might be accidentally disappeared from the application, export feature allows the user to have a backup copy of the file in the format of csv. Reason being why in excel format is because user might want to use the data for other purpose apart from backing up the data, and excel is a more readable and user-friendly way.
Export mechanism
The export mechanism is facilitated by XmlFileStorage
, which resides inside StorageManager
. It allows the user
to export either their addressbook or eventbook in a excel format.
Enhancement Proposed: New command import
As the problem is mentioned in the enhancement added (export), user might want to import their backup data into the app (in the case where the data is already gone and the user still have a backup copy due to the export feature).
Enhancement Proposed: Integrating to Online Platform such as Facebook, Google
Allowing the user to add their Facebook friends birthday into the event calendar, so as to make things convenient for the user to keep track of the date while not manually adding the events to the calendar (since the birthday date comes from Facebook, it will synchronise the birthday dates into the calendar).

THE SHINING RATING: 8.5 / 10 --> Really great movie
For more reviews and movie trivia, go to http://surf.to/joblo/
Terrifyingly, amazing achievement in filmmaking and the art of terror, this movie classic graces us with one of director Stanley Kubrick's sporatic directing gigs, only 5 years after his last acclaimed feature, BARRY LYNDON, and 10 before his timely masterpiece CLOCKWORK ORANGE (9/10). This movie is based on author Stephen King's best-selling novel of the same name, and stars the always-interesting Jack Nicholson.
PLOT: A nice man, his wife and young boy, take on the task of overlooking a winter resort during its off season. The nice man is there for peace and quiet, as his profession as a writer requires just that. The boy has a special skill called "the shine" which allows him to hear and see things that others cannot. As their time in the grand hotel ticks away, the mansion begins to exude thoughts of the past and chills of the present. In time, the nice man transforms into a "not-so-nice" man, and begins to terrify his own flesh and blood.
CRITIQUE: Chilling, majestic piece of cinematic fright, this film combines all the great elements of an intellectual thriller, with the grand vision of a director who has the instinctual capacity to pace a moody horror flick within the realm of his filmmaking genius that includes an eye for the original shot, an ice-cold soundtrack and an overall sense of dehumanization. This movie cuts through all the typical horror movies like a red-poker through a human eye, as it allows the viewer to not only feel the violence and psychosis of its protagonist, but appreciate the seed from which the derangement stems. One of the scariest things for people to face is the unknown and this film presents its plotting with just that thought in mind. The setting is perfect, in a desolate winter hideaway. The quietness of the moment is a character in itself, as the fermenting aggressor in Jack Torrance's mind wallows in this idle time, and breeds the devil's new playground.  This film is a perfect example of this very thought.
And it is within this film's subtle touches of the canvas, the clackity-clacks of the young boy's big wheel riding along the empty hallways of the hotel, the labyrinthian garden representing the mind's fine line between sane and insane, Kubrick's purposely transfixed editing inconsistencies, continuity errors and set mis-arrangements, that we discover a world guided by the righteous and tangible, but coaxed away by the powerful and unknown. I have never read the book upon which the film is based, but without that as a comparison point, I am proud to say that this is one of the most terrifying films that I have ever seen. I thought that the runtime of the film could've been cut by a little bit, but then again, I am not one of the most acclaimed directors in the history of film, so maybe I should keep my two-cent criticisms over a superb film, to myself. All in all, this movie captures your attention with its grand form and vision, ropes you in with some terror and eccentric direction, and ties you down and stabs you in the heart with its cold-eyed view of the man's mind gone overboard, creepy atmosphere and the loss of humanity.
Little Known Facts about this film and its stars: Jack Nicholson has been recorded as having really "lost it" during several filming scenes of this movie, as Kubrick's meticulously over-precise filming manner, apparently led to many takes (he demanded 127 takes from Shelley Duvall in one particular scene) and plenty of mind games. Jack apparently had to be physically restrained after one particularly famous scene, in which he was chopping into a door with an axe. Nicholson apparently ad-libbed the now-infamous line "Here's Johnny!" Jack Nicholson has also been quoted as saying about Kubrick: ""He gives a new meaning to the word meticulous". Kubrick apparently had Nicholson do fifty takes of a scene where he "simply" walks across the street. Author Stephen King was known to have disliked Kubrick's version of his novel, to the point where he himself decided to write a 6-hour made-for-TV version of it in 1997, starring Stephen Webber, of TV's "Wings" sitcom. King was never allowed to publicly denounce Kubrick's interpretation of his work, due to contractual clauses, but his version didn't fare much better with critics either. During the making of this movie, director Kubrick was known to have called author Stephen King up at 3am and ask him questions like "Do you believe in God?" Background on film: Stanley Kubrick had a large stack of books that he was looking through to find a movie project. For a couple of hours, his secretary could hear him pick up a book, read it for about a minute, and then hurl it into the wall. She then noticed that this hadn't happened in a while, so she went in to check on him, and found him reading Stephen King's "The Shining". King says that this is really strange, because the start of the book is very slow, and doesn't have much to do with the rest of the story. A fun site that some of you may want to visit, is the Ultimate Simpsons Stanley Kubrick Reference Archive at http://www.nh.ultranet.com/~mcollier/kubrick.html The many writers on TV's "The Simpsons" apparently follow and admire many of Mr. Kubrick greatest cinematic works. And is "The TITANIC an homage to THE SHINING?" Go to http://www.geocities.com/Hollywood/Theater/3181/titanic.html to find out. Timberline Lodge on Mt. Hood in Oregon, which was used for the exterior shots of this film (but not the interiors, which were all specially built), doesn't actually have the infamous "Room 237" from the movie, as the lodge owners' specifically requested the number 217 used in the book be changed to a nonexistent room number.
Review Date: December 25, 1998 Director: Stanley Kubrick Writer: Stanley Kubrick and Diane Johnson (based on a novel by Stephen King) Producer: Stanley Kubrick Actors: Jack Nicholson as Jack Torrance Shelley Duvall as Wendy Torrance Danny Lloyd as Danny Torrance Scatman Crothers as Dick Hallorann Genre: Thriller Year of Release: 1980

#### Q52. Why is unit testing harder in OOP than functional programming? - [✅] Objects may maintain internal state, which is not easily accessible by the tests. - [ ] The quality of unit testing frameworks for functional languages is better. - [ ] OOP promotes code reuse, which means that your tests have to consider more use cases. - [ ] Object-oriented languages tend to rely on frameworks such as Spring or Hibernate, which make them difficult to test.
#### Q53. What is the function of a user diagram? - [ ] It connects actors to use cases. - [✅] It links actors to roles played in all use cases. - [ ] It lists all actors for each use case. - [ ] It minimizes the number of actors required.
#### Q54. How do object behaviour and attributes differ? - [ ] Behaviour describe dynamic properties; attributes are static. - [✅] Attributes describ a state; behaviours describe a change. - [ ] Attributes apply only to a specified object; behaviour apply to other linked objects. - [ ] Behaviours are vector quantities; attributes are scalars.


Making a map
A friend recently got a Glowforge 3D Laser Printer and I offered to help him break it in. One of the examples from Glowforge is a really beautiful bathymetric map. We thought it would be fun to do something similar, but to include topographic data (elevation above sea level) in addition to the bathymetric data, to make a full relief map. After searching around a bit, we found this NOAA site that provides a wealth of relief data in the form of tiff images.
We decided to focus on the San Francisco Bay Area. The raw elevation above sea level is encoded in meters as pixel values, where negative indicates that pixel is under water. This is what the raw data look like rendered as a heatmap using the reviled jet color map: Turning this raw file into a vector image that the Glowforge could print turned out to be trivial using a handful of Python modules:- tifffile to read the raw data
- scipy to resize the image
- matplotlib to draw the contours and save them to an svg file
- numpy for a few simple manipulations
SFBayReliefModel uses data published by https://maps.ngdc.noaa.gov.
